When it comes down to making a decision based on the principle of double effect that actually is
exactly how it is done. I am in no way contradicting myself. The principal of double effect says that the good effect has to be proportional to or greater than the bad effect to make the action moral. This, of course, presumes that the means are not intrinsically evil and that the person acting in no way intends the bad effect. I may have phrased it differently but what I said in my previous post is
exactly how the principal of double effect works, which, along with the ends do not justify the means, are the two fundamental principals for determining morality. It is perfectly moral to perform a surgery on someone even when that surgery has a risk of killing that person when there is a greater risk of the person dying without that surgery, that is because of the principal of double effect, the good that can be reasonably expected from surgery is greater than the bad that can result from it. If the means are moral then the option of possibly saving a life, even if it brings risks, is a greater good than certain or even alll-but-certain death.
