Fai nuf, 'cause I'm bored I'll throw my two cents in here.
In being I'm not a believer of '***' as 'He' is 'known' I find the phrasing or point of this question redundant, but for the heck of it, if I were to be brought back (providing my passing wasn't physically destructive or terminal etc) I can't think of a reason I'd particularly want to return, in so much as I simply just flat-out don't want to die (nor do I want to live forever and see those I love around me pass on either, it's a catch 22) - but given the oppertunity it would be for the benefit of those I'd left behind like my mother and brother... not in the least my pets (the eldest going on 16 or 17 now, he is like a surrogate child in many respects) who would be lost without me - or so I'd like to think
I'm selfish enough in my reasons. I just wouldn't want to see my mum who's already have a hard enough trot at life suffer unduly if she didn't have to. Not natural for a parent to outlive their child, so if given the chance I'd say; let me live at least til she's gone, then she's none the wiser for the suffering and I can 'go' in 'peace' (if 'peace' is how you can label it)
Death and grief are natural aspects of life so the logical side of me doesn't wish to disrupt the natural flow of things. There's nothing inherantly remarkable about me, I haven't cured world cancer and I'm not in control of any world organisation or a figurehead for the betterment of mankind, so really what reason could there be for justifying my return anyway safe for selfishness?
