This thread is mostly just me being playful and bored, but I did find myself feeling sorry for him.
We don't know he is gay until he tells us the dead guy was his lover, which is just before you part ways. So the character has been well established as kind of a dick and unlikeable long before you discover his sexual preference. So I'd say they treat him that way and he is gay. So I am sure the writers intended the reveal that the girl stole items from him to be his comeuppance, jerk got what he deserved. But the scene where the girl revealed she stole his nudey magazine, laughed at the idea of him missing it at night, then unceremoniously tossed it out the window just made me annoyed at the girl. Yeah, he was a grumpy grump and a jerk, but he still risked his life to help her and then discovered the loss of someone important to him in the worst kind of way.
Stealing something that might be important to someone else just to destroy it for amusement, is cruel behavior and is only done to hurt someone. Stealing the comic book because she wanted to read it, or stealing weapons, food, or useful items is far more justifiable, even though it is selfishly motivated, at least it is serving a purpose. Taking something just to take something away from this person so that they don't have it anymore is far worse than selfish.
Everything done by this character prior to this point has gone toward liking the character and finding her somewhat endearing. I feel the writers took a misstep here. They probably intended this scene to be endearing as well, since the guy was an asshole. But they already gave this asshole character a gut wrenchingly bad day, then they have the protagonist do something shitty to him on top of it all, even though she should be grateful. He gave them guns from his private gun stash, risked his life, and sacrificed the only functioning car battery he knows of which could have been of great use to him, and all for their sakes.
