The difference between a hero and a villain

I am sitting here on this fine morning, and I asked myself, what is the difference between a hero and a villain? As I sit here, and wonder about this, my mind has become pregnant, and a thought was born, and that birthed thought was the answer I have come up with.

First of all, let's look at the "war" hero/villain role, because the fact of the matter is the only difference between a war hero, and a person who would be considered the villain is what ever side you want to win is the hero, and what ever side you want to lose is the villain.

To continue, let us look at a classic hero, Robin Hood, because most everyone knows the story of robin hood, but in case you some how do not know, and need a quick back story I shall tell you it: robin hood was a man that robed from the rich to give to the poor, so clearly he is a hero, because we all know the poor can use a break right, however on the other hand robin hood put the poor in danger, and the money he stole from the rich was what might have been used to build schools, hospitals, and so on, (before you say the might not have had that in those days, just go along as if they did) so he would be both a hero, and a villain, and I am pretty sure both the poor, and rich saw him as both.

pursuing this further, let's look at one last example. A man has a heart attack, and is saved by cpr by another person, however the man that had a heart attack is an axe murder, whom will might kill again, now is the person who saved him a hero for saving a life, or by allowing some that is a murder, and will do so again, a villain? TO the person he saved he is a hero, and maybe the murder will never kill again, because he was given another chance at life, so that person has saved lives, however on the contrary to the family, and friends of the people he killed the person that saved his life would be a villain for allowing him to live while their loved one is dead.

in final analysis, looking at the question; what is the difference between a hero, and a villain, it is easy to see that it all breaks down to a matter of opinion simply, because what is a hero to one person is a villain to another, and this is not just the examples I used, but this can be used for all most ever situation in life, besides crimes such as rape, and there is no true difference between the two, rather just how you as an individual looks at if someone is a hero, or a villain, and you will always, for the most part, see what is good in your eyes to be good, and what is bad to be bad.
