This is honestly one of the funniest questions I've seen yet; by which I mean, I can't tell if you're serious or not, and I'm not quite sure how to answer it.
Short answer, judging people is called a sin because when you judge people and decide that they're evil or horrible or beneath you, you: A) are ignoring/forgetting that God saw a lot of flaws in you too, and still gave you a second chance; and B) he tells us not to judge people as if we know whether or not they're going to hell or whatnot, because that's not our job, and its not our business. We shouldn't be trying to play God, that person's character and relationship in respects to God are between them and him. We're just being judgemental of them for no reason.
But, its not a sin to simply judge a person on a certain characteristic or their abilities… God doesn't exactly think talent show judges are bad. Or that people shouldn't judge how ready someone is to drive a car.
(Also btw, people don't go to hell cause they do certain bad things, its because humanity is broken and cut off from God in the first place. Getting home to God isn't a matter of being as good as you can, its a matter of taking the second chance he offers you that you couldn't ever deserve or earn on your own)
I just copied this and I understand this is a joke PS.
