(don't be so judgemental , you don't have to care about what they're doing even if that's quite bad for you just dont care about that as long as It's not tooooooo bad or something shouldn't be done like drug or kill people) 聼起來自然嗎?

Hello! This just sounds a little unnatural. Here is how I would phrase it...

Don’t be so judgmental. You don’t have to care about what they are doing. Even if what they are doing is bad, just don’t worry about it. As long as it’s not to bad or something that shouldn’t be done like using drugs or killing people.

Otherwise it was pretty good! Great job! 👍🏻
