Carl could barely stand you,now that he lost Glenn was even worse,he blamed you for everything.

even for Glenn's death when you literally didn't do anything, because he couldn't help but hate you with his whole will,you basically fought everyday.

you weren't hard on him,he still hated you tho, but you quickly understood that this was his way of getting over Glenn's death.

"and I just blame everything on you... at least you know that's what I'm good at"

he says in the middle of a fight.
