To demonstrate my point about infinite money having a finite value, what amount of money would you need to kill your mum? How much to slaughter your whole family?

And you can't say its impossible to value those things as they can certainly be ranked in order of value. Ie say, I'd rather just kill my father than kill all of my siblings and cousins, or w/e.

The fact is that for most sane people there are things in life more valuable than money. For some of us our own lives fall in to that category, for others it doesn't.
