I think it's wrong to tie poor behaviour in with the role.
There are good and bad in both seats. Some captains are so unprofessional and disdainful towards the SOPs (and the FO). Some captains are salt of the earth and people you would consider friends.
I am more than certain a number of FOs can be a pain, likewise I'm sure there are many decent individuals.
Same goes for the cabin crew down the back.
A lot of it depends on your base. Generally the bigger it is, the worse it is. Lots of dodgy individuals avoid detection simply due to how big the operation in the big bases is.
