My great aunt's husband (my great uncle) molested my mother and her sister when they were very small, and because they never said anything until 25 years later, and at that point my great aunt was dependent on his income, he never faced any kind of consequence, other than everyone finding out and hating him. He was a miserable person before this came out, and everyone hated him (even his wife) before they knew, so I really don't think that's retribution enough.
He's always made me feel uncomfortable, but I didn't find out what he had done until about a year ago (I'm 17)

Anyway we live in a trailer on their property, so their home is right next to mine. And I ended uo with the bedroom on the end of the trailer so I have the only window that faces their yard. Like I said, he makes me feel uncomfortable anyway so I got really freaked out when I started hearing him outside at 1, 2 in the morning when I am awake. (he has emphysema or something so he coughs a lot, and I am notorious for always staying up at night and sleeping during the day.) I told myself I was just being paranoid because my mother always made me feel like I was totally safe and my great aunt kept an eye on him too. I heard rustling near my window a few times so I had paranoid thoughts that he was watching me through my window, but I knew nobody could see through my curtain even with the light on because we had to have checked all those months ago when we put them up...
Well a couple weeks ago my mom's sister is coming over and she's all pale-faced when she comes inside and she says "Anon, you can see right into your bedroom." Of course I start crying, I go to check it out and you can see right in if you're looking, even from 20+ feet away, feel very unsafe because you know, that's my bedroom where I thought I was totally safe and private. We fixed it up so that you couldn't see in, and everyone told me not to dwell on what could have happened because it's over now, and I felt fine but I was getting paranoid that my great uncle might have actually been looking in as I'd feared. I went over to his house later because my grandma was there visiting and I had to help her with something, and when I walked in he was on the porch and he surely did say "new curtains, huh?"
He usually tries to be friendly with me, make small talk and stuff when he's out smoking and I'm out with my dogs, but he hasn't tried speaking to me again since, not even to say hey, so I know he was looking. Plus, I haven't heard him outside at night.

My family says he'll get his in Hell but that means nothing to me. His wife hates him, his daughter hates him, but that doesn't seem to bother him. Truly psychopathic, I guess. My great aunt is the best person any of us know, so I understand why he never got sent away, but I don't know what he deserves but he's not getting any of it, and he's retired now, so he is almost 100% useless yet he still gets a pacemaker and insulin injections and whatever else he needs to stay alive.
