No, ultimately friend and foe go extinct and the planet and sun die and there is no record of the good or the bad that evolution produces.

Then what exactly is the source of the compassion that you just boasted before me? At the end, they are simply nothing more than a speck of dust in the whole universe. The fact that the sun will die out someday does not really extinguish my sense of purpose.

You cant serve a greater purpose, you can only make life the purpose you chose for yourself.

No, this purpose was there before I was born, and will exist after I'm gone. It's greater than me in all regards.

"Greater purpose" no such thing never was, never will be. But when we say something like "The greatest generation, meaning the soldiers of the allies that defeated Hitler" It still wont long term be a given that this nation will stand, in fact boarders have never remained the same and powers shift. The Chinese have for thousands of years shared the same region, but they no longer have monarchies even if they have the same cultural memes and superstitions.

As I said, anything that outlasts me or the likes of me is greater than me. Generations come and go. Deeds, works, ideas, these are things that last. These are great.

What made the Allies great, wasnt an infinite ideology that would last forever, to me what they did was evolutionary, it appealed to the positive side of evolution in protecting the desire of individual freedom.

Indeed, this is why the Allies were not really great. They were simply more numerous, as they had Mother Russia and its minions at their side, who undervalues human life just as they did "individual freedom", or whatever you think that allies stood for.

But Hitler also thought he was doing the "nobal" thing.

And indeed he was. What can be more noble than to profess your love and undying gratitude to your nation? However, he was not really great at calculating his moves.

The dark side of evolution also produces alpha males that seem to do a good job of keeping things in line.

"Alpha males"? "Evolution"? I don't know where you're getting at, friend. It's not about keeping things in line. Ideals are not there to keep things in line. Ideals are there to make things go forward.

Maximizing benifit and minimizing harm is the only "greater purpose"

Indeed, that's what we all try to do. But it depends on the time scale. What seems to be harmful or not that profitable in a short timescale, might be benefitable in the long term. People with base minds will always seek small scale happiness, while people with ideals will seek greater benefits, and therefore, less harm.
However, there might be people who profess to ideals that always produce harm, and no benefit at all. Such ideals eventually die out.

The Nazis were wrong because their greater purpose was to save face and dominate without regard to who they hurt and their people

The Nazis were simply unsuccessful. In terms of ideals, I don't think that they were really that wrong. They did actually see realities in most things. Their actions were simply badly timed.
