Do you think that the people that don’t have or can’t get money the right way so they want to steal or kill for it?

So are you just asking whether this is what causes crime?  If so, that's a huge argument.  There are generally two sides to this.

Liberals tend to argue that people commit crimes largely for the reasons you gave.  They say that people commit crimes out of desperation because they don't have the opportunity to make a good living in a legal way.

Conservatives tend to argue that people commit crimes out of choice.  People commit crimes essentially because they are bad people and/or because the punishments don't scare them enough.

No one really KNOWS why people commit crimes, but these are two major theories.
