You must have some really flexible GM who allows you to get away with having an much higher level of darkness in your character compared to the RP itself. ;p
Liking dark RPs is one thing, claiming that darkness is realism is another. I own a very dark pokemon RP with no real limit on how dark you can get short of things too graphic for this forum at all or smut, but I acknowledge it's definitely not realistic in the sense that it takes liberties with what could happen in the pokemon canon, and it's also way darker than reality for that matter.
Tbqh, from the one SU I've ever actually judged of yours I'd have to say that your view of realism comes off as darker than the real thing, no offense.
I think what we have been disagreeing on here is personal views. My view on life is pretty dark; My parents divorced when I was only about 4 or 5 (I literally have maybe three memories of my childhood until I turned about 11 or 12), my mom keeps dating terrible guys and it's been affecting me, and generally people treated me rather poorly. But I'm not here for pity, and honestly I don't like talking about my problems. I figure no one would really care all that much... :/
Anyways, my point is, maybe my perspective on life is so dark because I've lived a dark life. It's what I'm used to, and it's what I consider realistic.
