does this make me a bad person

so i'm on a volleyball team and majority of the people on the team suck. like really really suck. half of them don't even know how to serve.

so recently we had a game and we lost. mind you this is our first game and we still aren't all the way comfortable with each other. we won our second game though (we had two games that day) so before our second game this girl we're going to call her M.

So M is like "omg all of yall suck i wish i was on the other team"

M is one of the girls that doesn't even play good. like she's really trash and doesn't call the fucking ball. so when she goes for it she gets mad when other people go for it too. like that's why you call the fucking ball.

so my friend is like "don't say that it was our first game we'll get em' next game"

M said "I don't care yall is trash so i'm going over to there team"

so i say "bitch your the reason we lost. you can't play for shit and when did we say we even wanted you on our team. also the other team probably wouldn't want you either. so sit the fuck down and humble yourself. bitch"

everybody was really shocked and some people started laughing. she looked like she was going to cry and i regretted saying it because i used to be trash like her and mess up all the time. but she really was getting on my nerves
