As far as we know, except for this planet, there are no atrocities, no disasters. Stars go supernova, galaxies collide, black holes suck anything close into them, all quite spectacular - no evil anywhere else to be observed in the physical universe. Yes it is possible, but that is not our fate.
In order to have an earth to dwell on, there must be tectonic plates, and hence there will be earthquakes. We will be bodily resurrected, and while I can imagine various scenarios as to how this is, it would be mere speculation. Suffice to say that if we are more grounded in existence itself, we are more real than are material manifestations of being. In that state we are immortal. In order to become more real, we must become more loving. We have to bring about the good by giving ourselves over to it. I’ve seen a lot of people sick, dying, dementing. In the end, what we don’t give over, will be taken from us. When we return to God this life, all our abilities and experiences, which he has granted, they are returned as a sense of peace, purpose and gratitude. This entire process is one of a flowering producing the seed allowing for our rebirth as completely eternal beings. We could have had this at the beginning, but we chose otherwise. Now we have a second chance in this world.
The loa loa nematode that causes filariasis adapted itself to living in the human organism through the same processes that are involved in producing the multitude of living forms on the planet. For it not to exist, would involve the elimination of this diversity. We cannot know to what extent God has intervened so that all humanity may not be infected and go blind, but this illness is permitted to exist because it offers us a choice to make as to whether we help one another. Humans are the primary reservoir and it is treatable medically and surgically. Another opportunity to do good and be transformed into goodness.
We were designed to think and argue, so that we can grow in knowledge and wisdom. As to your last paragraph, the only response that seems appropriate is “no reply”.
