Use of violence does not achieve just ends in the long run. What do you think about this statement?
It may be argued that tyrants and oppressors can be prevented from continuing to harm the populace only by being forcibly removed. Or the liberation struggles of oppressed people can be justified even though they may use some violence.
But resort to violence, however well meaning, could turn out to be self-defeating. Once deployed, it tends to spin out of control, leaving behind a trail of death and destruction.
