Are villains born or are they made?
Well why not both.
Perhaps we straddle being heroes and villains from birth to death.
And if anyone can be a hero, then anyone can be a villain.
Somedays we are heroes, some days we are villains.
And perhaps that is what Hamlet meant.
We are what we choose to be yet born to choose what we wish to be.
Good or Evil.
Thinking makes it so.
