Yes but crying over taking the pain away from a dying dog does not cancel out the fact that for most of the Season (and during the Season final) he acts like an arrogant ass. He’s just not as sensitive as fandom perceives him to be.
Remember that time he beat up that dude to get tickets to a rave or when the was all about killing Lydia.
How come Erica’s always depicted as strong and bitchy and sexy as hell - but Isaac isn’t? They pretty much act the same way for most of the Season.
