It’s like watching a train wreck waiting to happen, while everyone praise the madman conduct or who’s operating the locomotor at full steam.

I don't think that's diagnosis (as a clinical term); closer to defamation.

Is it necessary to a point you want to make?

You can just point to behavior of a given entity, such as to conclude it's untrustworthy, without the problematic area of armchair psychoanalysis.
