(NSFW) Should an act like this require psychological assessment?

This to me is the most sick and sadistic thing I’ve read in the news all week. A 62 year old man has been arrested for filling a lube dispenser with a corrosive acid at a Sydney gay night club.

My question is should he not be brought in for psychological assessment as a result of this act? Clearly this is not a person of sanity or rationality at all.
