It's funny.... I was into the same shit. Drugs, sex, guns, knives, sharp sticks, fast cars, doing really stupid shit in Detroit.... But I was never violent.
Up until I joined the Army, I'd only been in one fight in my life (when I was 10 IIRC), and by then I was 23. But I did talk my way out of many potential fights.... and when I walked away from an almost certain violence, I got a huge rush out of the adrenaline and stuff.
Not that I was totally defenseless. I knew how to use the blade and the sidearm, and I always carried both. Shit, it was Detroit, you never knew WTF a party night would bring. Never once though did I pull my gun or blade as a deterrent or threat, because that's an escalation of things, and how people get shot/stabbed with their own weapons. Almost nobody knew I carried a .357 Model 66 S&W, and a Sykes-Fairbairn dagger. The only time anyone would've seen them, would've been if I was seriously in trouble, and only then to use 'em.
But even without touching them.... when facing up to a totally dopefucked gack-freak, or a plain ol' belligerent drunk, just the knowledge that I had their lives in my hands (and they didn't know it) was intoxicating.
I still love pain, but only as long as *I* can control it, on my terms. And branding filled that niche perfectly. Hmmmmmmm
