On the surface,you could say that. But I agree with PS whole heartedly.
Looking between the lines is necessary when you look at a guy like Tony Montana.
When you look at it that way,you can see different things about him. He was only a man,who thought foolishly that he could have the world and when he got it, he later fell apart,and couldn't handle it.I look at him as being someone who did not want to be evil,or plan to be evil,knew that his life was no good for his sister,and struggled within himself to justify his own actions.
But yes,he was what he was,but I cannot see him as a monster.
To me,it all comes down to this:He was a victim of corruption in this world.
