I am a young teen and i often get obsessive over things that i cannot control or change. I always feel a sense of responsibility to fix peoples problems (even online) and i feel extremely overwhelmed when thinking about unfair opinions or laws and things that i cannot change. (Btw, the people in this example are people i don't know) On the site "Quora", this 12 y/o (Jenny) said she loves to embarrass her friend's 15 y/o brother (with her friend who is also 12 or 13). They apparently made him strip naked at a sleep over and tickled him and his privates. They also bare spanked him (because he spied on them while he was getting undressed. Someone actually told them they should do all of this when she asked what a punishment should be). The tickling thing is on my mind the most. I understand making a punishment of seeing him naked since he watched them get dressed, but it kinda comes off as molestation or something. And she really seems to find an interest in embarrasing boys. A lot of people in the comments seem to kind this funny, but you shouldn't get in the habit of touching someone innaproiately to embarrass them as punishment. If this were to happen to a girl, this wouldnt be okayyyy. So it just made me sad to see people thought this was a good thing. But anyways, he's said on some q&a's and in the comments of her (Jenny's) answers, he said it was embarrasing (he said it was embarrasing that he had to get naked, but didn't really talk about them touching him). I asked him "are you good?" on his profile and he said "no not really, my stepsister is still in charge of my punishments" with a few emojis and it came off kinda jokey-not serious. His profile also says "slave to anna" (his stepsister) and that came off like a joke too.
Anywaysssss, how do i just push this outta my mind? This was all recent. I know i obviously cant change it and its not my job to tell the girl she shouldnt do this (which i still did), but it still makes me sad. And i don't even know if he feels super affected by it, but still. I would hope that since he's a 15 year old, he's able to stick up for himself if he really needs to. What do you think about this and how to i stop thinking about it? (This happens a lot and I'm tryna work on understanding that it's not my responsibility to fix random people's problems. It kinda puts a weight on me)
Worrying if people don't answer. 
Don't know what to do anymore.
