I think its all very objective. I maintain my morales when it suits, but when the time comes to throw down the gauntlet and just have done with it all, that is exactly what i do.
I wouldn't try and cite an example(not a proper one anyway), because its a complex issue and i havent got all day to write the events leading up to during and after any decision i might make.
I will however, for the sake of adding discussion mention charities:
If you have money to spare, or spare (call it currency for lack of a better word, whether it be books or whatever) currency, should you give that which you do not need to charity?
Should i donate a percentage of my earnings to starving children i have never and will never meet? What about to one of the millions of charities set up all doing the exact same thing, but trying to do it their own way and in turn costing a damn sight more than it should for a pretty meagre goal.
Should i help people hit by natural disaster, or plague, or whatever in some distant land when there are homeless people within my own society and country less than 5 miles away?
I help where i can, but there comes a point when i have to say, really?
Look at say, a charity (not fair to pick one out) that deals with dementia, should i ever find myself with dementia (serious case) i will happily take my own life. Why? No quality of life, i would hope i wouldn't become a burden on my loved ones, or to the society i am a part of, i would hope that some carer, would focus their efforts on saving those who can be saved, not a lost cause like me. Will i ever donate to a dementia charity? No, unless they are specifically looking for a cure, you can count me out.
Don't get me wrong, in an ideal world i'd love to help, but at this point, logic > morals
I read a story once of how an Inuit elder, when they realise they can no longer contribute to the family either through chewing leather or hunting or whatever, simply walk out into a snow storm. No prompt. No dragging on and hanging about, they just get on with it so as not to be a burden. Which strikes me as one of the most selfless acts anyone could do.
