Shylock... A Villain?

I believe Shylock is a villain in the play. As the audience, we see Shylock wanting revenge on all Christians and taking it out on only Antonio. But in Shylocks defense, he was affronted by Antonio and simply wanted to be able to get revenge like anyone else. All of the ribald comments and jokes made Shylock defensive to the world. I believe he only wants the best for his daughter but he also cares about money. He is trying to show all the Christians that he, as a jew, should not be trampled on. He is also looking to take a pound of Antonios flesh, which will kill him. I believe he does this as not only revenge for Antonio but also to all Christians who ridicule Jews. So in all Shylock is the nefarious character in the play, but it is due to the actions of the Christians.
