>There will never be any greater evil emerging if kikes are destroyed.
You are optimistic, at least from my point of view.
That optimism may be rooted in the idea that the evil of the jews is purely a material evil, a genetic evil, with no further ramification, nor any deeper source.
My point of view is based instead on the idea that the evil of the jews is foremost a spiritual evil, rather than only of material evil, even if the spiritual evil can and has corrupted also the material level for the jews. And that spiritual evil wouldn't really be affected by a total eradication of the jews, since the jews would be only a visible manifestation of the deeper invisible evil, and once the jews are removed that spiritual evil will find new ways to show up its ugly face in the material realm.
This doesn't mean that the jews shouldn't be opposed or dominated, just to be ready to kick out and hold advantage over any and all expressions of that deeper evil, everytime it will show up, even after the jews are gone. And also if that evil will show up in some populations which aren't related to the jews.

There is actually a non spiritual way to explain what I'm thinking about, it just came to mind now, I'll propose this interpretation too.
Even if this materialistic downgrade of a spiritual concept lacks nuance, and should be taken only as an example, and not the entirety of the discourse.

Think about the material evil of the jews, be it of genetic origin, if you like. If you go back far in the past, where did that genetic evil come from? It came from a random mutation. Random mutations happen all the time, that randomness is what allows humanity to slowly change, and that little change when coupled with selection, is what allows more favorable human setups to advance and to allow humanity to adapt to differing conditions.
But that same very useful and very important randomness, is also the source of horrors, of which the jews can be said to be a great example of.
Do you think that randomness "decides" to affect only the jews, and no one else, ever for all eternity? Surely that randomness affects everyone, every human population. And since that randomness affects everyone, the same "errors" or material evils which made the jews what they are, could appear potentially into any other population.
So even after the jews would be gone forever, that randomness will still be with all of us, and eventually some other jew-like horrors will emerge into non-jewish populations, and maybe even go unnoticed for some time before being found out which could allow a new jew-like population to take stage in history. And there is nothing which can really be done about it, because any attempt to limit that randomness would result in less variability and less ability for humanity to adapt, which lack of adaptability would dangerously weaken all humanity, making humanity more vulnerable to a mass extinction event.

A similar alternative re-interpretation of the spiritual evil, could be done by using a sociologicial evil as metaphor, instead of a genetic evil.
Evil behaviour, corrupting the body, the body further corrupting behaviour, in a cycle of evil self-reinforcement. And that evil behavior emerging out of random minor events and accidents. So that behavioral evil could reappear anywhere into any population, anytime in the future. Where that randomness of tiny events can't be removed, lest all humanity be reduced to some gray and grotesque existence, leading to the end of all humanity.
