I feel so bad

guys I made this friend online and I thought he was pretty cool but when I added him on social media he turned out to be so fkcing ugly almost looks like a predator rat with a flattened head and recessed chin. I'm so sad for him but I cannot be friends with him anymore I'm so scared of his head
I've started cold replying to his shit and I feel so bad but HES SO UGLY it's unbearable I can't imagine myself being friends with him
