The only influence you might say they have is from not being around. Maybe that helped cause Dally to be so angry.
Explanation:
the reason he is by himself is because of his parents neglect, he is a very troubled person. I suppose that maybe he came to be this way because his parents didn't care about him. Dallas Winston's personality has definitely been influenced by his parents or, more specifically, the lack of parenting in his life.
If Dally had had any parenting or been shown kindness by anyone (before the Greasers), he probably would not have ended up in jail at the age of ten. If he had not been forced to live on the streets, he probably could have allowed himself to be soft.
