How "evil" are the Diamonds?

ven if you take the given idea that humanity = the fundamental 'good' that must always be respected as such out of the equation, the Diamond treatment of the Gems on Earth was pretty evil. Also it seems increasingly apparent that the 'winner' of the war to save humanity possibly won that because the loser didn't even consider eradicating humans to be a goal. Who won the war really? The remaining Gems on Earth appear to all fall into a category of having lost a great deal: (the first part of this list is taken from an anon on /co/) The gems we have met have been: Cracked and put inside an inanimate object, treated as such for the next few thousand years corrupted, without sense of self and raging about the world for the next few thousand years shattered, incomplete, possibly in constant pain, cursed to always look and look and look for a way, any way to be complete again for the next few thousand years - before being bound into servitude to the Diamond as a eldritch horror fusion monster Alive but isolated, living in a world not your own, unable to really connect with those who live there and always dwelling in the past mistakes of your race for the next few thousand years safe from being forced to unfuse and free to be with the one you love for thousands of years but at the price of having to constantly labor to protect life from the mess the war left guilty of having caused all of the Gem mess to come about and also having the only tools to handle the damage done -- but still victoriously allowed to enjoy the beauty and worth of the planet and humans saved. Basically Rose won the war AND she got what she wanted: humans to love and play with. Garnet won the war and got the right to love herself and exist. Everyone else was punished rather horribly. Everyone else is unhappy and damaged. But when looking at the damage done to the Gems is it the Diamonds who are worse for having come up with this sort of punishing war outcome or Rose for having not only starting the war but having spent the last 4000 years trying to teach her followers that the victory and planet SHE had won was worth it?
