Am I the bad one for calling my ex-friend a slut and saying she deserves to die?

So, I have a very good male friend and used to have an ex female friend. Recently I found a new group and started hanging out with them and purposefully didn't invite her because there was a guy in that group persistently interested in her despite her having her boyfriend. This led to her thinking I was excluding her (I didn't clarify my intentions until we had a fight and was tired of constantly explaining myself). Anyways, she caused a miscommunication between my male friend and I by misunderstanding some of the words we said about each other, and both of us lashed out at her for it. She kept insisting it wasn't intentional and what both of us said sounded very vague, but we didn't wanna hear it and told her boyfriend she drinks with us and was harrassed by the guys in our friend group while being drunk. We told him she wears body hugging clothes, doesn't have control over how much she drinks and out of anger, lied about her regularly hanging out with those guys even when she doesn't and only does when we are there with her. I know we're wrong there, but are we really wrong in implying that she's a sl3t who deserves to die and doesn't deserve friends or a boyfriend?

Edit: We found out she called my male friend a Playboy because he goes on many dates, and we further said that she's a sl3t so she doesn't get to dictate who's a Playboy and who isn't.

Edit 2: The guy who kept hitting on her said that she went out for a movie with him, but she says she never did. She's insisting it repeatedly, but we find that hard to believe.
