Doubts

The world ran on mutual benefit, and as long as Karim could show that he would benefit the youths more than the Wolf Gang or whoever else they were working under, they'd be willing to work for him.

And with that in mind, Karim made many promises that he was starting to doubt that he could keep, but would do everything possible to do so.

Through that, he was preparing well, and when the time came, he seemed sure that he'd be able to stop the Wolf Gang's distribution and all those he was in contact with would go into hiding.

When that happened, the Wolf Gang couldn't afford to go after all the youths and wouldn't benefit from doing so, which would leave them holding a large amount of goods that they were unable to distribute.

Leaving them with such goods for a while and cutting off as many of their other money streams simultaneously, including the Wild Dog Fight Club, Xavier could deal them a large blow.
