Draco Malfoy is perhaps the darkest and shadiest character to feature in the Harry Potter books after Severus Snape. Honestly, Draco is not likeable throughout the course of the seven books because of his unfair meanness and prejudiced notions against the golden trio.
But it is not unreasonable. I think if no one remembers, Harry and Draco's animosity began with the fact that Draco insulted Ron on their first meeting at Hogwarts.
Now why did he do that?! Let's get to that point.
We all can see that Lucius Malfoy is an absolute insensitive, cold monster. He is blinded by his prejudices against the mud bloods and muggles. He is an ego maniac, who couldn't care less about his son's feelings. He had always fed Draco what is good or bad according to his judgement. Arthur Weasley and Lucius work in the ministry and its obvious how open minded Arthur is and how much interested he is in the muggles, which is entirely opposite for Lucius. The hatred was passed on to Draco through Lucius. Honestly I believe Draco is more jealous of Ron, and the Weasleys than he actually hates them. Everyone knows how accepting and loving the Weasleys are. Living in a cold environment as such as the Malfoy manor, with talks of the Dark Lord and death and genocide...., a child seeks love and warmth in a home. Time from his family. Care and affection. And he was completely ignored and kind of isolated from those pleasures because of his father and his queer obsession with propriety. Thus his unbound hatred for the Weasleys.
Draco knew that his father likes being friends with influential people, thus he knew being friends with Harry Potter would earn him some appreciation in the least, if not love. But with his quick negative remark about Ron and his family lost him Harry's friendship. Thus with every mistake Draco just grew bitter and bitter until the very end. He wanted to be better than Harry Potter. He wanted to be more popular than him. He wanted to be as loved as Ron Weasley was by his family. He wanted a true friend who cares for him like Hermoine Granger does for Harry and Ron, and not have blind followers like Crabbe and Goyle from familial obligations. He wanted to Slytherin to win the house cup and gain genuine favor from the teachers. He wanted some one to care for him like Hagrid. He wanted his father to care about him and his opinions and feelings. He wanted a normal life with happiness. But no. He didn't, he just lost and lost and lost. And that made him bitter and more envious and loathsome.
He never wanted the life that he had to live. He was afraid of the Dark Lord.
Draco was mean and selfish but not evil. His selfishness triggers his cruelty and coldness but he is not evil. He didn't wish to kill Dumbledore and he even couldn't see people dying. He was positively disturbed when a person was killed infront of him at the Malfoy manor. He didn't wish Harry or his friends to die, because however much he hated them, or pretended that he was superior to them, they were his friends. He was genuinely scared for them. He didn't wish more people to die. So he pretended that he didn't recognize Harry.
Later on he went to retrieve the cup and fight against them, but that is because he had no choice.
Draco Malfoy didn't have a choice.
Draco has done a lot of bad and unforgivable things but in no way he deserves to die. Some people say that "Draco Malfoy should have died" and stuff but I think that is absolutely unnecessary. I believe he got his chance at redemption and peace. He had to live on, the rest of his life, with trauma, regret and shame. That was both his punishment and relief. No more expectations and the Dark Lord. Just him and some space to breathe and live life like a normal wizard with a family to care for.
But because he was not evil, he could slowly revive from his bitterness. It was clearly mentioned that he had acknowledged Harry and the other's presence while having his son board the Hogwarts Express. He felt ashamed so he couldn't approach, but he was thankful so he did acknowledge them.
He is definitely a person who's character got destroyed purely due to the circumstances and his poor environment, like that of Tom Riddle Jr's, but he should not be blindly hated. He is a dark character and in no way should he be mistaken to be soft and kind and genuine. He is arrogant, mean and rude, but that doesn't make him cruel. Atleast not as much as certain people claim him to be. I am not a Draco Malfoy fan, but I always judge a character's both good and bad and I can appreciate the good. Recently I read a lot of hate comments which were absolutely unnecessary. He has done many many unforgivable things and he has recieved his punishment as well. He would never be able to look up with the other wizards and witches ever. But,
Draco deserves to be loved. Draco deserves happiness and peace.
Hopefully in an another alternate universe, Harry would find out why Draco is so mean. Would eventually fight with him then punch the truth out of him, help him cry, tell him that it is ok you be vulnerable and that no one is pitying him and that he would love to be friends with him if he would be nice to Ron and then would be friends with him. Draco would apologize to Ron. Hermoine will forgive. Ron will take time but eventually they will develop a wierd, awkward but cute bromance and the others soon will accept him. Okay, now i am rambling.....you can leave...ulp...
PS : Atleast for the poor childhood he had there must be a proper compensation and recovery, because tht was the only thing which was not in his control. We all have a choice, always, but that was something where he genuinely could do nothing. Thus that's where my empathy arises for him.
