Why are survivors like this, man? (Storytime/rant)

So, I have a friend who just got into DBD, she decided to pick up killer and she found the most joy in playing Oni (Who has a really high skill ceiling for new players but let her enjoy whatever she wants ig), but she's still new so needless to say she isn't really good at keeping up with survivors so since I'm a bit more experienced in DBD I asked her to record and send me her gameplay footage so that I can take a look and tell her what she's doing wrong etc. and oh my god, I'm probably over overexaggerating but the footage is genuinely heart breaking, survivors destroying her is one thing because even myself as a player with 2k+ hours I get destroyed, but they literally act like little sadistic pricks when they see a killer that has no clue what they're doing, not only they're bagging her like their life depends on it but the worst thing I saw, they 99'd the gates and instead of just you know getting a 4 man out and going next, wanna know what they did instead? They literally stayed in the match and kept forcing her to chase them and keeping looping her instead of leaving, like holy shit the audacity to not only be toxic towards a killer who genuinely has no clue what they're doing, but also staying in the match for longer just to poke more fun at them? Genuinely toxic behavior, and she wasn't even doing ANYTHING to deserve a treatment like that (Not tunneling or camping or slugging) just literally a new killer trying to enjoy their match despite of their mistakes, but it doesn't end here, they even went out of their way to leave comments on her profile where they insult her for being "trash" etc. And my only question is, why? why would you wanna do that? how much of an insecure little rat do you have to be, to go out of your way, to completely ruin a new player's match but also take the bullying outside the game, besides the hell did they do to you other than trying to enjoy the game? Geez, what world do we live in.
