Convincing Bear to take over the Rusty Hooks gives the player the chance to redeem them – i.e. make them a legitimate, non-raiding group.
If the player can do any of the non-lethal disabling the heart bomb quests, then the player can convince Bear to take over the Rusty Hooks. Bear will not attempt a takeover if he knows his heart bomb is still functional and Kyle has control of it. Having Bear as the leader of the Rusty Hooks gives the player the opportunity to convert the raiders from a criminal organization to a legitimate organization. With all the materials present at Bloomfield, the Rusty Hooks could make out pretty well as a major manufacturer of metal goods and establish important trade routes.

Combat Boy, Diplomacy Boy, Science Boy, Stealth Boy – As long as Bear is safe from his heart bomb, it's pretty easy to talk him into it.
