At what point does ignorance become evil

Assuming the people involved have a high enough HD, what should the members of this wacko cult detect as?

The members of this cult have come to the conclusion (mostly by having lived through some really bad and violent times) that life, in general, is suffering. Whether there is a greedy and uncaring aristocracy that refuses to help the starving peasants, or malicious raiders who kill and enslave any who can't defend themselves, or scheming devils who attempt to warp and corrupt everything you love into depravity, life is, in their view, defined by suffering. What simple pleasures can be had in life are just temporary reprieves for most before the suffering resumes. The cult believes that just solving the immediate crises plaguing the people isn't enough, as a new generation is born and they will surely suffer as well when a new crisis arrives. No, in order to break the karmic cycle of suffering, to transcend mortal suffering, life must end. The good souls will get their eternal reward in the heavens, free from suffering, and the evil souls that have been malicious causing others to suffer will suffer their just rewards as well in the lower planes. As they see things, in the afterlife, common causes of suffering like,hunger, disease, warring kingdoms, etc are, for the most part, just not a factor. To that end, the cult has decided that the most efficient way to do so is with a special disease they've concocted. Is painless even as it weakens and kills the body. They offer a message of peace and hope to anyone who would listen, and actively oppose any groups or individuals (even in the face of personal peril) that would cause suffering to others, even as they wait for their disease to spread and end life. They do not do this with any expectations of reward or gain, but merely because they believe this is the right thing to do.

The alignment rules state:

Quote:

Good implies altruism, respect for life, and a concern for the dignity of sentient beings. Good characters make personal sacrifices to help others.

Evil implies hurting, oppressing, and killing others. Some evil creatures simply have no compassion for others and kill without qualms if doing so is convenient. Others actively pursue evil, killing for sport or out of duty to some evil deity or master.

This cult could arguably check off the list for Altruism and Concern for the dignity of sentient beings (although yes, there may be a bit of cognitive dissonance in their beliefs), as they make personal sacrifices to help others. Of course they do not have Respect for Life. Their entire philosophy disrespects Living as a way of life (no pun intended).

This cult does kill, of course, primarily through spreading their disease, but they don't do it out of sport, or do it out of convenience to get something else they want. They do end up hurting people, since killing off members of society deceases society's ability to function, not to mention the mental anguish of people losing loved ones. The cult doesn't quite see it that way of course, or perhaps some members see it like the pain of a needle to inject a necessary medicine. there is pain, but it is for a beneficial situation later. Regarding oppression, not only do they not do they, they actively oppose it.

Their intent is arguably good, but the side effect (everyone being dead) is probably not good. But, they do try to minimize suffering on the way to their desired end. So, how should the objective morality of the universe label these cultists?
