Shylock: EVIL JEW or miserable victim

The Villain
1. Vindictive
He imperils the happiness of Venetian businessmen
Antonio: I oft deliver'd from his forfeitures Many that have at times made moan to me

2. Selfish
He curbs the will of his daughter and appears to have complete disregard of her
Shylock: I would have my daughter dead at my foot, and the jewels in her ear! Would she were hearsed at my foot, and the ducats in her coffin!

3. Cruel and bloodthirsty
He shows mercilessness and bloodlust towards Antonio in spite of his pleas for mercy.
Shylock: If I can catch him upon the hip, I will feed fat the ancient grudge I bear him.

Murder is not justifiable. He may have his reasons for villany, but in the end, one cannot justify murder as revenge. There can be no valid excuse for taking another person's life.

The Victim
1. Moulded by circumstances
Shylock's attitude is the result of unfortunate circumstances; He is shunned by Christians in an anti-Semitic world
Shylock: You call me misbeliever, cut-throoat dog, And spit upon my Jewish gaberdine

2 Unfairly treated
The 'mercy' rendered unto Shylock is not truly magnanimous. Chirstian mercy seems to be cruelty under a guise.

3. Forced to bear great suffering
Loses a daughter, wealth and property to a Chirstian.

Thus, it is not right to sayb that Shylock was a villian that got his just desserts. Maybe he was just a victim of his villainy.
