Dexter has never been intentionally malicious to anyone, not even Callum. He's messed with him sarcastically, but not in a way intended to truly hurt him (contrary to Callum reading into every little thing he said or did).

I don't think any of the others could say that. They may not do it to their faces, but they've all said things that they may need to answer for once they've left. It's similar to how they kept accusing Dexter of gossiping when he was saying, "I've heard xyz about you, be careful" while they were all running around naming names.
