WIBTA if I hooked up with a boy knowing he likes my friend

I'm planning on trying to hookup tonight with this boy that I'm friends with. I just found out that he likes my friend. He barely even knows her, and she barely even knows him. So WIBTA if I still tried to hook up with him knowing he wants her. Idk what if there's a chance she's interested in him too and I'm getting in a way of their potential relationship, but I also decided I wanted to hookup with him before knowing this information.
