It's the same thing with street gangs, some people just want to belong to something and have an identity and a purpose.
And some love an adrenaline rush, always involved in crimes or fights. That's why they even shoplift lol to get the adrenaline going.
That Jack Garcia told a funny one when Greg De Palma at like 75-80 years old was in a store hiding things in his jacket stealing them, like cheap shit. And Jack called him out and he just said he couldn't help himself he loved it
Even Renato Vallanzasca a feared killer in 1970s-1980s was arrested recently because was caught stealing underwear during the day release ,I wouldn't call it an adrenaline rush but more a squalid thing.
