Should Dally Winston be considered as a hero after helping save the children in the church or should Johnny get all the credit?

Your answer to this may depend upon your interpretation of Dally Winston's character in general and his specific intentions when he enters the church.  How do we define a hero?  Also, how do we evaluate Dally?  It seems as though all that really matters to the reckless Dally is Johnny.  If Johnny had not entered the church, Dally would not have entered the church.  He accomplished a heroic act of helping to save children, but he only did so in order to assist Johnny, the one person in the world for whom he is willing to die.  It seems that to give Johnny the credit would be the right and noble thing, since it is Johnny who initiates the heroic act, and also inspires Dally to help. Dally wants to show the world that he does not care.  He does not care about laws or offending "Soc" girls.  However, he cannot hide that he cares about the group's "kid brother" Johnny.
