Because Goku was training, he hadn't experienced the "Earth Defense Battle" game and therefore didn't know about Ginyu's ability.
Krillin knew about it, but he didn't realize Goku was unaware. And since things happened so fast, he didn't have time to warn Goku.
Ginyu was mentally rejected by Kakarot inside Goku's body and had no choice but to transfer.
Taking advantage of this, Kakarot viciously beat Krillin. He had disliked Krillin for a long time (actually, he disliked everyone) and thoroughly enjoyed throwing Ginyu's spirit into Krillin's body. Then, when Krillin's spirit entered Goku's body, Kakarot suppressed it.
After that, Kakarot went on to mercilessly thrash Jeice, Burter, Recoome, Guldo, and Krillin (in Ginyu's body)!
Finally, he bound them all up along with Goku and Krillin... It wasn't that he didn't want to kill the Ginyu Force — it was just that he couldn't be sure what Old Man Taro was thinking. Without knowing if the old guy wanted to spare their lives, Kakarot didn't dare to kill lightly.
He was scared!
To Kakarot, Taro was an overwhelming shadow branded on his heart since childhood.

"You guys really are something," Hathaway said with a shake of her head.
Kakarot (Krillin) awkwardly said, "Master's wife, I know it's embarrassing... but it's because of this guy!" He turned and pointed at Ginyu (Goku), who had been untied by Gohan: "Didn't even figure out Ginyu's ability! Too arrogant!"
"I already apologized!" Ginyu (Goku) protested.
"Humph!" Bulma stroked her son's head and shot Ginyu (Goku) a sideways glance. "You're punished. Tonight, you're going with Sun Gosen to play 'Earth Defense Battle' on the virtual Earth network!"
"Really?" Sun Gosen blinked, instinctively looking at Kakarot (Krillin), then his little head was turned by his mother to look at Ginyu (Goku).
Ginyu (Goku) knew he was in the wrong and nodded, "Alright then..."
Bulma turned to Hathaway: "Okay, Grandma Hathaway, where's Grandpa Taro? Where is he?" She muttered softly, "Looking like that, he's so ugly!"
Sun Gosen pumped his little fists in agreement: "Yeah, so ugly!"
Hathaway smiled and pointed toward the northern and southern skies, saying, "He went off to handle some things with Fabeli..." She glanced at the five Ginyu Force members tied up on the ground and the silent Vegeta nearby, then chuckled, "...collecting some little gifts specially sent by Frieza."
"Hmph..." The five Ginyu Force members, tied up in a heap, sneered coldly at her, thinking this woman was crazy.
Vegeta was confused too but didn't ask. He was in a dazed state right now!
Goku?
Kakarot?
Who was who?
Ginyu, with his body-switching ability, roughly understood... But if Goku was in Ginyu's body, and Ginyu was now in the bald Earthling's body, then the result should be that the bald Earthling was now in Goku's body.
But... just a moment ago, he clearly saw two different people on the face of this "Goku"!
The first was when he just returned, giving off the authentic Saiyan aura!
And now... this one had none of that aura! It was like an entirely different person! No, maybe it actually was a different person!
Two people existed inside Goku's body?!
Vegeta's mind was a mess.
Hathaway and the others seemed about to leave. Vegeta clenched his fist, stepped forward, and suddenly shouted, "Kakarot!"
Bulma and the others turned back.
"Hm?" Kakarot (Krillin) looked puzzled and asked Gohan and the others, "By the way, this guy is also from Frieza's army, right? How did you handle him?"
Vegeta's body tensed, full of vigilance.
"Together with those others. We'll deal with it when Master returns," Gohan replied.
"Oh." Kakarot (Krillin) nodded.
Vegeta sighed in relief. If a fight broke out now... he remembered the weight of Gohan's hand on his shoulder right after eating the Senzu bean. And even that bird... looking at the Phoenix, even that bird, he wasn't confident he could win!
Kakarot (Krillin) was about to turn away.
"Kakarot!" Vegeta shouted again.
"I heard you, I heard you. What's with all the yelling?" Kakarot (Krillin) muttered. His gaze lingered for a few seconds on the brown furry tail wrapped around Vegeta's waist. Of course, he recognized the tail immediately.
He also knew that his good brother Goku was a Saiyan, an alien whose race was destroyed and who was brought to Earth by Master Taro.
So, this guy in front of him must be one of Goku's surviving Saiyan brethren?
Yeah, that means Kakarot's.
Vegeta grit his teeth and asked, "What exactly is going on? Goku, Kakarot—who is who? Who truly owns this body right now? Which one of them is really the Saiyan?!"
"That question's pretty complicated..." Kakarot (Krillin) scratched his head; the feeling of hair on it still felt strange to him.
He glanced at Ginyu (Goku), who said, "He's looking for Kakarot, right?"
"Alright then..." Kakarot (Krillin) looked over at Bulma, who was watching coldly. "Hey, Bulma, can you let Kakarot out?"
Bulma pursed her lips and casually called out, "Stand up!"
Immediately, the light in Kakarot's (Krillin's) eyes dimmed. His clear gaze deepened as if a storm of rage and thunder was brewing inside. His eyes shifted coldly toward Bulma, showing a ruthless expression...
Bulma met Kakarot's stare, unflinching. "Why are you glaring at me?"
Kakarot sneered, "One day, I'm going to kill you!"
Bulma smirked back—she'd never been afraid of anyone in her life.
Strutting boldly up to Kakarot, she placed her hands on her hips, chin raised. "I'm standing right here. You say you can sense ki, but I'm just a weak woman. And as for my husband's strength—you've experienced it yourself," she said, nodding toward the grimacing Ginyu (Goku) over there. "With the power in this body, you could kill me with just a flick of your finger. So... come on, kill me then!"
Kakarot's anger blazed inside him. He glanced around at Gohan, Hathaway, and the Phoenix—all watching coldly. Taking a deep breath, he closed his eyes and let out a grunt, his mood unclear.
Bulma snorted and turned back, picking up her son and giving him a quick kiss.
"So, you're Kakarot?" Vegeta finally asked.
"None of your damn business!" Kakarot snapped, eyes still closed, clearly in a foul mood.
Vegeta's forehead twitched as he pressed, "You share one body with that Goku... Are you the same person?"
"None of your damn business!" Kakarot repeated.
Vegeta coldly said, "As long as you're Saiyans, it's my business! I'm the Saiyan Prince..."
Kakarot cut him off, "None of my damn business! Saiyan Prince? The Saiyan homeworld was destroyed by Frieza. What kind of prince are you? What a damn fool!"
"Frieza destroyed Planet Vegeta?" Vegeta's expression instantly darkened. "Planet Vegeta was destroyed by a meteor—"
Kakarot interrupted again, "None of my damn business! Am I obligated to explain things to you? Keep rambling and I'll kill you!"
He opened his eyes, looking coldly at Vegeta. This body's combat power had been forged in the gravity room, reaching 2.4 million—only in the final moments had it triggered the Saiyan near-death trait, unleashing all accumulated potential.
That kind of strength pressed down on Vegeta's heart like a mountain, tightening it with a cold grip.
Vegeta fell silent.
At that moment, someone spoke behind them: "Everyone's here, just in time..."
Vegeta's eyes suddenly widened!!
That voice?!!
Isn't that Burely's voice?
The same one who talked with the God of Destruction Beerus back in the mountain cave?!
He whipped his head around—
