If I understand this correctly, it wasn't a mission gone wrong but rather a pre-meditated act by one guy.
I would agree with the terms sick and disturbed but based on what little I know so far I think that it is a bit of a leap to call him "evil". First off, he gave himself up for punishment opposed to nicking someone else's rifle and doing it. Secondly he "only" killed everyone in two houses. I imagine he could have killed a far greater number if he'd wanted to.

Although it is possible that he joined the army, worked his way up from the ranks in some 10 year strategy to kill two families, but it seems much more likely that he is sick and disturbed by what he's been through.
