No, i don't symphathize with the Joker. The Joker is an evil person, he take people's lives lightly. He harbours evil intentions and he has no qualms about killing people. He robs the bank, and he is very selfish. After his acquaintences help him rob the bank, he killed all of them to keep all the money to himself.

I learnt that not all friends are honest and true. Some of them are pretending to be friends to take advantage of us and make use of us. I also learnt that to achieve something you can't give up easily and even though you failed a lot of times you still have to try again and again to succeed. You also have to learn to be smart to do work so that you would not get outwitted easily. Just like the Joker and Batman, I learnt that determination is important. Batman does not give up his pursuit to Joker, and Joker shows his determination when he was persistent to rob the bank.
