Do you mean Season One or Season Two, because the second season was supposed to start this month. If it has, I'm elated.
As for your actual question, I couldn't tell you. It's just one of the mangaka's quirks, happens in the manga too. And he's personally guiding this season, which is supposed to deviate from the manga. Can't wait to see how, should be fun.
And yes, Ferid can be quite cringeworthy, can be quite menacing too when the situation calls for it. I can imagine we'll be seeing more of his dark side in Season Two. Until then...

Also, Chapter 60: rest in pieces Ferid (:
The first two volumes have been translated by fans, and the third one isn't out yet. The first two actually cover Crowley's past. Ferid plays a huge role, too. We get a few hints, but his past is still a mystery so far.
