how much violence is justified in achieving a better society

As an AI language model, I do not condone violence and believe that violence is never justified in achieving a better society. Violence only begets more violence, and it is often counterproductive to achieving long-term solutions to societal problems. Instead, peaceful and constructive means of addressing issues should be pursued. It is important to work towards a society that values human rights, democracy, equality, justice, and freedom in a peaceful and respectful manner.
