In The Vampire Diaries Damon Salvator seems like he’s the main character psychological problems coming back from his past. In the show Damon in one on the characters to be cold hearted and devious in all aspects. At that point everyone should know that he isn’t the way he is because he wants to but something in his past made him the way he is now. In one of the episodes from The Vampire Diaries they tell how Damon became a cold hearted vampire. To inform even further Damon has a brother, Stefan Salvator, whom he’s very close to that got turned into a vampire first. Since being a vampire was very new to Stefan he had the urge to do ungrateful things to people that lead him to turning Damon into a vampire as well. After that Stefan had shown Damon how to be a real vampire and convinced him into hunting various of innocent people. However, before and after Damon was turned he was as innocent and a very warm hearted person until someone and something triggered him in becoming something he didn’t knew was in him. We all know some people change and let that past overcome them or let it pass through them; what Damon did was that It let him overcome who he was and turned him into a cold hearted person.
Damon is now a vicious alcoholic and blood drinking vampire whom his only desire is to kill and hate who ever stands his way of doing things. That’s the physiological behavior outcome of Damon Salvator’s past and who he’s become now. However, later in the seasons Damon seems to finally get the girl of his dreams to love her which seemed to be a huge therapy work for him and his life. As love has concord him he now cares much more of others than himself. His girlfriend, Elena Gilbert, has a very open and expressed mind that had lead her to many friendships that make her feel as id she was part of a family. Now that Damon observes her caring for others and how much they matter to her he tends to do the same. Ever time there is a friend of hers that seeks help, Damon is always willing to help and even sacrifice himself to save others just so Elena can be happy.
I’m not saying Damon has changed completely for the best because he always has his desires to kill and hate people but he now knows how to control them with the help of Elena. At times there might be some major things that can trigger Damon in being the monster he knows he is and lets him take pride for what he does. If he seems that there is no other option but to kill someone to get the work done then we will gladly do it without questioning. However, to others there might be another way to solve the conflict that might take some time but Damon prefers quick and easy. Sometime it takes the right person to let the good in you come out like his girlfriend Elena. Elena not always accepts the way he does things so she comes in and makes sure he does the right things so everyone will be pleased and not get hurt. At the very end of the seasons he end up doing something very from the bottom of his heart which is saving Elena’s best friend Bonny over he. If he would of saved Elena than he knew it would be selfish of him to keep her after he knew that Elena would rather choose to keep Bonny alive and not her. So Damon decided to save Bonny and not the love of his life because his mind knew that it would be the right thing; maybe not for him but for the people around him. To be I believe that is huge progress from his physiological past.
