The world is a better place because of Sam & his devoted advocacy of Peace & the truth. If one half of one per cent of Earth's population worked for what Sam did and as well as Sam did we'd now have Peace on this planet. Sam's stay on this planet was one of the most successful, worthwhile ones. He and his work should be held up to all people - children & adults - as the epitomy of a role model.
Also, coming from a totally non-religious person [me], there's a huge amount of documentation that death is not the end, it's just a transition. Sam is every bit as much alive as he ever was.
