- My Wife died, and I'll do anything to get her back. If I can't get her back, I want to punish those that caused her death. I want them to know the pain I have gone through.
- They took my pet, I'll take my revenge.
- I'm different, and because of that I've been treated badly. Oppressed, put down, second class. I'll show them all that I'm better than all of them, I'll make them pay.
- I was going to join the resistance/militia before they decided I'd make a better prostitute than soldier.
- God has seen fit to punish me, taken everything from me, as he punished Job. I will return the favor tenfold.
- My friends and comrades died for an agenda that they didn't believe in. In death they were dishonored, their names were stricken. I will not let so many heroes be written off as political inconveniences.
- I'm not an addict, I could quit at any time, I can quit at any time. It hasn't changed me, I am who I want to be. Don't judge me, DON'T JUDGE ME!
- I am the last of my kind
- It's not my fault, I was raised in an abusive evil lifestyle. If I was not evil, they would have killed me.
- It's my job, I hurt people, I break things. These things have to be done, if not by me, then someone else. That doesn't mean I'm bad. I love my wife and family. Nothing personal.
- I was born a freak, a monster. I was always treated like a freak, a monster. Don't be surprised now that I'm the monster you all claimed I was.
- I'm dying of a horrible recurring cough. You don't know what it is like knowing that your own death is coming, that the clock is running out.
- I can't help myself. I have these horrible inhuman urges. I can feel it running through me like fire. I want to stop but I cant!
- They took my mother from me, I miss my mother so much!
- They destroyed my home, those ignorant bastards. They destroyed everything, and everyone I knew fled or died.
- I have wronged so many people in the past, it started with my parents and just went from there. Soon everyone was wary of me, I was untrustworthy. Once no one trusts you, you just get used to using and screwing everyone.
- I was raised by wolves
- The poison courses forever through my body. I can take antidotes, they stave off the effects for a while. They don't do anything for the pain. Causing pain, now that, that makes me forget my pain.
- They took me as a child, and they reprogrammed me in a camp, they made me into a robot for their cause and then wrapped a human skin around that programming so convincing that I even believed that I was normal.
- I was going to be someone before my career ending injury
- My nation lost the war, but the thing the winners never realized is that for some of us, the war will never end
- I was adopted at a child, and knew nothing of my parents. I searched for them, and found out that it was because of you and yours that I was left an orphan.
- Better them than me, better them than us. They've had the upper hand so long they don't know what to do when the table turns.
- They left me for dead, but I very inconveniently forgot to remain dead. Oops.
- I've been places you've only heard of, I'm done things you can't imagine, and you think you can lecture me?
- I keep telling you these seemingly insane and improbable stories, but can't you see, they all really happened!
- I've lived for centuries, somehow I've had the gift of immortality. Let me tell you about the time Napoleon and I were at the Citadel.
- You don't know man, you can't know. You'll never know! You weren't there, in the mud and the rain, with the screaming and the dying, and the blood on your hands and that cold feeling in your gut just waiting for the grim reaper to come and take you!
- Let me tell you about how I met your mentor/master and how we traveled together before you lot came along.
- There was nothing happy, only gray and hard work. Then, there was the moment, the event, and I escaped, and I swore I would never go back to that again!
