I think it's obvious he totally cares for Bellamy, I think he was just frustrated with him (hence the him dying only comment). That's how I read it, anyway. I don't for one second believe he would be fine with Bellamy dying, we saw his reaction earlier when he got super aggravated at the prospect. At the end of the day, Murphy is always looking after Murphy. I do wish he'd show a little compassion about Clarke, but then again maybe I shouldn't be expecting that from him
