Was Alden a fool to throw himself so willingly into the jaws of death?
…Not really.
He didn't think so.
After all, it wasn't like he had lost all reason and was blindly attacking the vast horde.
No, Alden had backup.
And while it wasn't the most trustworthy, it was better than nothing.
Furthermore, he had Celeste back there too.
She was much more effective when given enough distance to show off her impressive prowess with the bow. Alden, however, was the opposite - he was much more dangerous up close and personal, where his insidious ability shone.
He was glad that his precious love had listened to him. This way, he didn't have to worry about her safety while fighting. And the decision had the bonus of also playing to her strengths!
It was a win-win. With this, both parties should be happy.
