Are Good and Evil Objective?

It would further utilitarian goals to release a murderer who’s very unlikely to continue murdering others but is very likely to contribute to society if released. You believe society can judge some mentally ill people to be capable of future good and release them for that reason and then when I give the example of a person who murdered someone out of revenge but is unlikely to ever repeat it for whatever reason, you turn around and say

Not necessarily. If you’re an adult and you murdered your former caregiver for a reason that could only happen because they were your caregiver, then it may or may not be reasonable, depending on the specific details of that situation, to assume they won’t just keep murdering people. It can’t be proven with certainty but it can be proven beyond a certain amount of doubt that would be acceptable for the purpose of informing the decision to imprison them or let them go

You’re telling me that if the chances of the prisoner causing more harm than good or more good than harm if released are equal and the net gain of inaction is 0 then you should choose the option with the net gain of 0. In that example, the option with the net gain of 0 was not releasing the prisoner. However, if the chances of the prisoner being more beneficial or more harmful are still the same but this time the action being considered is whether or not to imprison the prisoner in the first place, then by the same logic we should do nothing

Okay. The point still stands

That’s not a valid basis. I can compress your list of possibilities even more and make something like this:

  1. You release the prisoner and fewer people are harmed than benefitted
  2. You releasing the prisoner and more people are harmed than benefitted
  3. You don’t release the prisoner

I could even converge all of this into one possibility and call it a logical whole but speaking of logical holes,

Am I supposed to believe you didn’t split the possibility of attempting something into attempting that thing and failing and attempting it and succeeding?

You could’ve made it into

  1. more people are lost from the attempt than are saved
  2. less people are lost from the attempt than are saved

Relevance?

People under the poverty line in america can still have a much higher standard of living than the vast majority of native americans could before our expansion. We do see a lack of access to some modern medicines but this would still be much worse if the americas remained relatively underdeveloped which is what would have to come from us not being able to use force to extend our influence there

but this does not follow. A consequentialist would only care based on the effects of these things. These actions wouldn’t be inherently bad for utilitarian goals which is why I said the people who decry our invasion of the americas have the understanding that people will recognize the invasion as unjust without referencing a cost-benefit analysis or denying that much improvement has resulted from it. In addition, in the case of our expansion to the pacific, we did have utilitarian goals in mind when we invaded which you can see in the doctrine of manifest destiny. This is obvious from the iconic painting associated with manifest destiny, “american progress”.

It wasn’t. For the most part, the people who got land benefitted

This isn’t much of a counterargument but I’m sure you already know that, as you’ve already admitted you don’t believe any of this

I’ve tried interpreting this different ways and I can’t see how you got that conclusion
