I don't even know why you people are discussing this
(Way to quote out of context, people!)
General framework, ideal, principle... create a principle with variables
a,
b, and
c, and define what action is taken when
a,
b, and
c are specific quantities, and that principle can then be used to instantly determine the desired outcome where variables
a,
b, and
c have specific values.
Simple.
In this case...
"Would you kill [I decided to let the action itself not be a variable]
'x' for '
y' amount of money [I also decided to not let the reward be a variable, because that would allow for too many options]?"
For each plausible
x, create a lower bound for
y, where if
y is greater than or equal to the lower bound, the answer in relation to
x is yes. If there is no lower bound, then
y in relation to
x is infinity, therefore the answer in relation to
x is no.
