Just a little of my 2 cents, behaviours are not always choices, some people begining at childhood can grow up in an environment (at home) developing certain behaviours, and not knowing any different. Unfortunately as adults certain behaviours become a person's personality
I can also agree too that yes,what you said behaviour can be by choice, so it isn't necessarily a "black and white", there is some grey areas into what accounts for behaviours.
Take care,
