Any thing has a price.

even killing himself mother do has a price. since you can first take half of the money, treat you mother very well in many years, so good that she want to die too, than killing her. i think someone may think it is not a bad idea.

sounds crazy, hah~

A thing must exist some things else to trade, even your lover, your faith, your priceless stuff.

people may be NOT willing to see or admit this. but it is how the world working. this trading theory, especially work if you are in trouble. we can see a lot of stories base on this: a financial manger is facing stock market crisis, he need a lot money right now, at that time, he even accept a lower price compare to normal situation, just for getting some money. a girl lose her love, she may act differently, like crazy shopping to "help" herself. (oh, in fact, a lot of girl like money more than their love, especially after she grow up). there are many many cases.

this does not happen in ourselves, is because we are safe (and of course, no one has that amount of money). so that our needs low. however, even when we are safe. an incredible price can also affect our judge. lets say, 100 billion USD, to trade your current girl friend. or become a king, by kill your brother. or, return the earth environment to be balance and get 10 billion, by killing 10 people (you can give that 10 billion to the 10 people).

however, some people, we will call them "cheap", is because, their price is cheap. for 10 dollars, they can kill, they can cheat, they can selling their soul, which are not normal to most people.

so, noble or evil, may be judge by the cost. noble has a very high price. evil, may be even negative price.

well, it does not work so good. since it depend on what is "good", or "bad".
