He'd be a great addition to the new mane 6 (if there will be a 6th). Be great to have that one friend who just isn't "with it" like the others. He could learn about being a better pony by messing up a lot.
But his actions are a result of his upbringing and the environment he grew up in.
It's like the Fishman arc in One Piece. Nothing ever happened to Sprout, no Unicorn or Pegasus ever wronged him. But he was always taught to fear and hate them.
If he wasn't so detestable, it'd be a stretch to say he wanted to be the hero and be lioved and admired by being the one to "save" his village from the other races. We can see how jealous he is of Hitch.
