It's sometimes necessary to use violence in order to create disincentives for it, and discourage others from engaging in it.

Ghandi is a good guy and all, but he isn't always right:

I would like you to lay down the arms you have as being useless for saving you or humanity. You will invite Herr Hitler and Signor Mussolini to take what they want of the countries you call your possessions...If these gentlemen choose to occupy your homes, you will vacate them. If they do not give you free passage out, you will allow yourselves, man, woman, and child, to be slaughtered, but you will refuse to owe allegiance to them. - Ghandi, 1940

As a side note, it's spelled Gandhi, not Ghandi.
