People who are outright violent will want to maintain their evil ways, so they naturally will resist, so the creation of the system of mental unity would have to be protected
so that people can finally live peacefully without their terror; it will be unfortunate if some have to die resisting, but those who do not die will get the chance to live peacefully as well once the system is complete.
As for those who are killed out of defense for world peace, it will be no different from any other situation in which the greater good needs to be protected; for example, when a crazed gunman is shooting up a public place
full of innocent people, and he clearly demonstrates that he will not relent, he himself is best to be shot in order to protect those innocents, and it is indeed highly lamentable that he would have to die just because the malconditioning of his life
raised him to make such violent decisions. However, it is simply the terrible way of the world today that a person will be given unfortunate life circumstances that mentally damage him or her and ultimately prove detrimental to those around
him or her.
Plus, consider that the Fourteenth Dalai Lama, in his 1999 book Ethics for the New Millennium (published by Riverhead Books), wrote the following after discussing the phenomenon of modern warfare, whereby the elites who start wars do so almost solely to the detriment of people besides themselves:
"In view of this, I could see developing a 'smart' bullet that could seek out those who decide [to wage] wars in the first place. That would
seem to me more fair, and on these grounds I would welcome a weapon that eliminated the decision-makers while leaving the innocent unharmed" (205).
Even one of the most peaceful individuals on Earth understands that some people are better off dead than persisting in the destruction they cause for others. Of course it would be best
if they were simply reformed to live compassionately, but until mental unity is created, this simply isn't always feasible.
As the world is now, tough
decisions simply have to be made to protect the greater good, and, as in the gunman example, it is not person A's fault if person B creates a situation in which, no matter what person A does, bad things will happen, but if person A is knowingly able to minimize
the bad, such is his or her responsibility. "Sacrifice", therefore, is sometimes necessary, but it is not intrinsically villainous; in fact, in these cases it is simply a response to the restrictions imposed on us by the
villains. Back to my idea, however, mental unity will completely restructure society so that the highest fairness is granted to absolutely everybody, and violent situations will be avoided completely.
The more people who listen to me now and understand
this goodness of mental unity, the less resistance there will be in the first place.
