I,m sure they believe that they are undertaking their evil actions for a higher purpose but we all know, the smallest and the oldest of us that killing in all religions is strictly wrong, there are no excuses in any of the holy books I have browsed through that excuse the killing of innocents, in fact people who kill for dogmatic reasons and not self defence outside of a war are always labelled murderers and rightly so, even war is an obscenity we are told is somehow acceptable but it never is, when men or woman of peace act true to their faiths and not just to small parts of it taken out of context we may move on to a better world but for now we can only hope for peace and do our part to each other to make that peace strong around us.
I believe those who have passed on are never forgotten as long their friends and family take the time to discuss and contemplate their life's achievements, dying is always just a small part of ones time on the earth and a time of grief but there should always be time to remember the joy and times of important emotional interaction with each of those left behind to carry on, love never dies.
