Who said I'm condoning their behavior?
First, thank you for correcting the record. This is why the extremely harmful outliers need to be addressed first. The implications of moraity based soley on goals have been ignored.
But to answer your question: YOU condoned it:
I disagree, if these things were always wrong then they would never happen.
If they're not "always wrong", then sometimes they're right. That is condoning murder, rape, and kidnapping under certain circumstances. If that's not intended, great! But that's what your words mean, and that is the implication of a moral system that is derived purely from personal interest and goals.
I believe people choose to take the best action for themselves considering their goals at the time. Their morals are defined by their goals.
OK. That's a scaled back version of what you said in the OP. In the OP you go further and define "good" and "bad"
Morals are dependent on what your goals are.
"Good" actions are whatever furthers your goals.
"Bad" is whatever obstructs you from your goals.
If your actions get me closer to my goals, then your actions are good.
If your actions make my goals harder to reach, then your actions are bad.
To me, this makes it simple to judge good/bad actions.
No. The criminally insane are encouraged to pursue their goals as good. This system encourages / allows / condones all manner of heinous action.
This is most easily seen imagining a primitive hermit. This could be an actual hermit in the woods, or it could be a social recluse. The hermit/recluse wanders to a far away homestead and finds another hermit/recluse and kills them for pleasure and leaves.
There are only two sets of goals to consider. The hermit murderer and the hermit victim. The murderer deems the action "good" per the standard in the OP. The victim deems the action "bad". Based on the system described, that's a draw. It's neither good, nor bad, its neutral. That's condoning murder. It works the same for the other catagorical wrongs.
For me sure but those are my morals. Other people have a different set of morals so choose to act differently.
Only for you? Are you sure?
Let's maybe discuss the example of rape-as-a-weapon in WWII that you brought up. How can it be described as "good"? What are the details? Was it justified? Was it nessessary? If the soldiers did not rape, what are the "bad" things which would have resulted for them?
Those people are not making morals decisions for you. They are making moral decision for themselves.
Rapists Murders Kidnappers cannot be trusted to make moral decisions for themselves. These extreme outliers need to be excluded from a moral system based purely on individual goals. That's why a list of "don'ts" is required.
