I have not reached the end of the game, but thus far I've run into several NPCs that I took enjoyment out of flatlining. I'm talking NPCs that got under my skin enough that I HOPED I'd get an option to do them in, and when I got it I thoroughly enjoyed it.
- Woodman- He was a pig and I'd have killed him given the chance whether Judy asked me to or not. But he's the weakest of the ones I've encountered so far. The guy screamed "KILL ME!" from your first meeting. He's the kind of guy in real life that dozens of people would fill with lead if given the chance.
- Maiko- I wanted to beat the snot of her every time she was around. When the chance/option to flatline her came up I'm only sorry it was too easy.
- Brigitte/Placide- The first playthrough I had I was wary of not being able to get more missions from them. But that was soon after launch. Recently after reading stuff I'd heard that it wouldn't make a difference...so when given the option to pay them back for being douchebag liars and backstabbers? Man, I made sure I headshotted both of them and their minions. They (so far) get first place in NPCs I'd have paid eddies for a chance to smoke.
