Reef safe? Should I keep it?

Hairy with black claws no good and likely a member of the Xanthidae family which is very undesirable. Please post future pics under white light intensity for clear i.d.
Could be actual gorilla crab

This thing scared the crap out of me. It was under my hammer coral.
With better light may very well be emerald - member of mithrax group in which I dont trust them around coral but can be good algae feeders

Yeah, that's an Emerald Crab or close relative - they're just about as reef-safe as crabs get, but they (particularly the male crabs) can sometimes stop being reef-safe when they get larger.

So, mostly reef-safe, and lots of people buy them on purpose, but you may have different results with individual crabs.

Hopefully these are better. I want to make sure he does not eat my coral.
