I don't think trimming would solve the issue with the boy the way his toes are angled. It is almost like the guy has too short of tendons in his toes. If you tried to trim them so his toes touched, you'd most certainly hit the bone/blood in those nails. They seem pretty well worn down as is from walking on them.
I'd cull him if you didn't need him for anything and he's just an extra. As for a pet, don't think his funky toes would be much of an issue.
