In the Outsiders, Dally changed from someone who didn't care, wasn't law-abiding, didn't show his true emotions, and seemed to not have a heart to someone who cared and he even cried when Johnny died. I know this because in the beginning of the book, he stole from lots and lots of shops and acted all tough but then towards the end of the book, when Johnny was dying Dally was extra caring and visited him lots and when he did die, he cried and couldn't handle it so he killed himself.
