Killing in the name of any cause, undermines the cause and defines that cause in a distorted light. We may all believe in a cause but understand that applying pressure to achieve a change through many other forms other than violence is the right way to go. Even Tibetans under threat of constant torture and death from China resist violent opposition and extreme terrorism. Rather they sacrifice their own lives to highlight their plight and cause. When you turn to violence you lose the right to identify with any cause, you just become another brutal callous murderer and nothing more. Only when faced with the threat to your own life or those close to you, is it reasonable to respond likewise. Murder is never a answer to anything.
