You start with something small. Stealing tips off a table. Spitting in the communal punch bowl. You can key someone's car - just little 'fuck your day up' shit. If you like the way it settles, you keep going. You pull a wallet from a lady's purse. You start taking things that don't belong to you.
If you stick with this program of gradual escalation, you will, eventually, make it to the big leagues. Your torture and murder - that kind of thing. Manipulation. Emotional theft. These are the fields of discontent you can traipse through. Innocence can be plucked in any season.
Eventually, you will flame out. You will become overconfident or paranoid or both. You will give into your baser instincts. You will develop addictions and other crutches. You will be ruined the way you have ruined others.
This is your legacy.
