What are your thoughts on your husband being friends with a cheater?

My husband has a close friend from childhood named Cedric. They became friends at daycare and Cedric lived with him on and off again because his mom was always losing custody. Cedric is "nice" per say. But he's a serial cheater. Every girl he gets with he cheats on. He also has a heroin addiction. He's slept with men(and surprisingly even a few women) to pay for his addiction. My husband has had to set a few boundaries with Cedric which is don't introduce him to any girlfriends because it just feels wrong knowing he will cheat and don't come over when he's high. He said he can call him when he's high, FaceTime him when he's high. He just doesn't want him over our home when he's high. I was cheated on multiple multiple times but an abusive ex and it just triggers me. My husband said Cedric has just had an awful life and while he doesn't agree with anything he does, he's not gonna just abandon him and he would probably end up killing himself. Cedric grew up with a drug addict mother and suffered abuse from her boyfriend which she chose over him. The boyfriend also was inappropriate with him which I get it. I was raped when I was younger. But I'm not out hurting other people because I was hurt. It just bothers me that my husband is friends with someone with such crap Morales.
