Well, thats a totally different thing. I find everybody can have their reasons for refusing to donate..thats all cool.
But lazyness! Thats is not a good reason for not donating. I remember when we all got the letter turning 18 in school and almost everybody would say 'ow uhh yeah..I still have to fill it in...' and months later is was still the same..
My opinion just is that its a the organs are so useful after dying, its a pity to leave them in empty soulless shell.
And yeah..if your death is good for anything, it will at least me something good to other people. God will appreciate that as well ;)
