No. I believe morality is universal. This does not suggest that the far-reaching consequences of your actions align with the morality of those actions. I think Julius Caesar was pretty consistently a scumbag. I also think he has had a profoundly positive effect on history. This is not a contradiction, you are inserting your own suppositions into my beliefs.
The greatest results are the greatest reduction of evil. This is not necessarily accomplished on a large scale by one person acting morally, because again, you are not privy to the ultimate consequences of your actions beforehand. However, you can largely eliminate the evil you are directly responsible for. Perhaps this paves the way for greater good or greater evil in the next generation, this is mindless speculation. Perhaps what we all ought to do is act more like Julius Caesar. Mindless speculation. Your control is extremely limited.
You asked me what I believe, so I told you. You seem to now be arguing that I do not believe those things. This is strange behavior.
you don't understand the issue, you have not determined what the 'good' (ontological status of 'good') is and you have no epistemic justification of that good, your attempt at justification (justification is not what something is, but how we know it is the case) for this undefined "good" is "reason" but I have given the example that limited human reason can give two separate people opposite conclusions on what the "good" is so for it to be universal it cannot simply be subjective and this requires a normative authority. you reject a normative authority, and even reject 'oughts' which makes your entire claim of objective morality as a universal to collapse completely.
when you say " I think Julius Caesar was pretty consistently a scumbag. I also think he has had a profoundly positive effect on history." it is a psychological report followed by an ontogically empty claim of the status of "positive effect". to say something has a positive effect requires there to be a universal we can point to that is 'positive', a moral universal which you have still not shown the status of. you are smuggling in transcendental categories which have metaphysical baggage but you are ignoring the metaphysical baggage.
"The greatest results are the greatest reduction of evil." is an empty statement, you have not given the ontological status on "greatest" or the metaphysical status of "evil" (as I personally do not believe evil has an ontological status but this isn't relevant).
What is evil? What is great? How do you know this is the case? without answering these basic questions this statement is an empty platitude that collapses under basic philosophical scrutiny.
"This is not necessarily accomplished on a large scale by one person acting morally,"
this again applies to "acting morally". what is "acting morally" should we act morally only if the consequences are "good"? whatever "good" means. how do you know this is the case?
"largely eliminate the evil"
again, what is evil and why ought we eliminate evil?
I'm not saying what you feel is not what you feel, I am saying your worldview is rationally incoherent.
