I mentioned it a few times in OOC, but my neutral evil tiefling actually bonded a bit with a leaver's paladin. Here's the gist of it:
I lead her out of town to kill her. Player has been salty about me being evil and not sharing my sheet with everyone else. So I thought: "I can justify killing her because she thinks I'm a devil worshipper and she knows buddy is a vampire and didn't act. Perfect reason for killing her: silence." I end up taking her to the river as she was supposed to be back before sundown (as promised. And the river runs through town). So I spend several times trying to get her to go near the riverside so it would be easier to push her in, steal her stuff and say owlbears attacked us and took her body away before I could get to it, with her later on in the day, her body appearing in the river and shock and horror strike everyone as she has several puncture wounds from an owlbear (as there is a problem with them and I have a beak of one) and her valuables would be taken by me and her armour would have been left in the woods.
So I had this elaborate plan, and I even brought my apprentice (long story) with me in case she starts kicking my ass. Then the unthinkable happens: in my attempts to get her to come close, she starts joking around with me and during this time, I even start Sharing backstory stuff to get her to come closer so I can kill her with my magic. Unfortunately, as a player, and as a character, I did end up caring because she was actually leaving the island we were on and probably going to die (monsters and a maelstrom stopped all passage to and from the island) and her calls on her god protecting her brought my character back to his parents who were clerics of Tempus who said the same thing when his brother came the same day to kill them as well as my brother. I immediately snap to shouting that the gods didn't save my brother when he needed them most (he was just as devout to them and was in training to become a cleric himself (my character worshipped Tempus as well, but not as much.)). This unleashed so much feeling and emotion that I couldn't bring myself to kill the paladin. So what happens? DM gives the paladin's Magic sword to my apprentice and since I have no player reason to kill her, and I acutely felt bad for doing this, I LET HER GO.
I can never hold my head high, knowing that my character for a split second, returned to his good natured roots. (In regards to my character: my character was born into a very devout family of Tempus with one troublemaker brother and one goody-two shoes brother. The goody one protected me often from the other one who hated me because he thought he was forgotten. Years later, he kills my brother when he found out that his own brother was part of a thief gang. He later slays my parents who, as I said, claimed their God would save them, and they died. I made it out alive by hiding, but then hate filled my body and I wanted revenge, and the only way to get power as fast as I needed it was to make a deal with Asmodeus to become a warlock. I ended up hunting down thief gangs and killing everyone trying to find answers, or his location, but nothing. The shadow thieves got wind of my killings, paid me for the work I did for them without asking and offered me a job as their hitman in taking out rival gangs. I accepted only to find my brother, but again, to no avail.
So how my character acts is he's a fall from grace character who is doing what he sees as good (killing criminals) in order to find his brother. But the way how he is doing it is bad (I played too much hotline maimi when I made him, so think of his killings like that, but magic instead of guns and no masks, just clever disguises). My character is busted often in his dreams by three people (another hotline Miami reference) where one is his brother in an Asmodeus worshipper' mask (rasmus), another is his mother in a Tempus worshipper's mask (don cornero) and himself behind a raven queen worshipper's mask (Richard). They all have the same personalities, and the dreams happen the same way as they do in hotline maimi, except it's D&D and Richard does it every time I either level up (as the DM put it) or when I commit a major evil act. The Raven (as I call the Richard parallel) came alone on the last one saying I'm digging a deeper grave for myself in hell when I got my pact blade. It's a different way of being conflicted with morals, but it works. The DM is also doing a great job with the dreams I have of Hell, my patron contacting me and those dreams (sadly, I get one of them every night, meaning I never get a good dream sleep)
