I mean, purestorm is being pretty blunt but I agree with him here.

Even if you didn't mean harm by putting his dead dog in his locker, that's just disgusting. Maybe you meant well, but why couldn't you have put the dog somewhere for him to get later and then found him to explain. The way of dealing with it was just unfair and cruel seeming.

I don't blame him for being angry and upset by how you approached that at all no matter how you intended it.

And even if that never happened or even if he would forgive you, why on earth would you want more? He used to bully you. He clearly doesn't like you. You shouldn't go near someone who treats you badly and think it'll be better if only you can convince him to like you. It's like hoping he'll go from disliking you and treating you badly to liking you and treating you like a princess. People don't usually change like that.

I'd honestly stay far away from this guy. Not you have said makes me think that doing otherwise will be anything but a recipe for disaster.
