Bottle-reared adults can be a complete pain to humans, whatever their gender. You do need to teach him manners and respect, no shoving or jumping up, etc, if you intend to keep him on. And if he won't learn (which is entirely possible if he's used to being pushy), you will end up sending him to the abattoir anyway, either before or after he damages someone. Sorry.
I keep a few wethers in my flock - it's a fleece-and-meat flock, not everyone needs to be a breeder - and they're no problem to the ewes. However a) they were all castrated as youngsters and I don't know if castrating at one year old leaves them more hormonal and tup-acting, and b) I find it better to not leave the wethers in when the tup comes. Assuming you'll have a 'weaned lambs' group the wether can be with while you tup, the latter shouldn't be an issue?
