Re:

Then why should I work with. Him

I think you should work with an on this. I don't/can't trust him, and the fact that you do is fine, of course, but I can't. He is a bad guy who cares only about himself.

You told me to approach him on ██████. I don't trust him at all

I know, I did. Though he could be useful. I just have such negative feelings -- not so much an open wound any more, but still a bruise.
