i feel shitty

so there’s a kid in an organization i take part in who’s way younger than i am (he’s an eighth grader and i’m a junior in high school). he’s not the best at socializing and i don’t really talk to him if i don’t have to. he’s in a group chat with some other kids and i though and he spoiled the ending of the new stranger things season and i told him that he shouldn’t have done that and it was actually pretty rude. however, how i actually put it was “literally don’t do that unless you want to get deleted.” I meant it as a joke (using deleted in place of murdered because it seemed worse to use the latter) and then another kid in the group chat kicked him out. later on this girl said that i was being pretty harsh and i basically i feel really shitty.... but at the same time i don’t feel like i’m in the wrong because i was trying to be honest and i wasn’t actually meaning to delete him, someone else did it. and also i don’t.... really like how unaware of everything he is :\ ..... i feel like he needs to open his eyes..... but i also didn’t like how she thought i seemed rude because i don’t want people to think i’m rude!!!! because i wasn’t trying to be!!!!! i wanted to be honest because i didn’t like that he did that (albeit i knew what happened) and it wasn’t fair to the others and some people thought i had a point but also he’s really small and i just don’t know how to feel so i’m probably just gonna cry and feel like a shitty person :\
