In the face of unbearable, inexplicable or unjustifiable suffering, there are three responses.
The first says: This life is not all there is. There is another world, after death. There is heaven. There is peace and eternal life. All the evil of this world is banished in the world to come.
The second response is to see, as did John Keats, that this world is ‘a vale of soul-making’. We suffer so that we can grow. Others suffer so that we can practise charity or kindness. The bad in our lives is an invitation to the good. For that is how we become morally responsible agents.
The third response is to say: There is evil, therefore there is no God and no ultimate meaning. There is no justice, therefore there is no judge. The world is as it is. Homo hominis lupus est, man is wolf to man. The world is a restless searching for power after power that ceaseth only in death, as Hobbes said.
Always remember to a religious zealots it is always god(s) will!
That is their patent response to anything that happens to them, their families, their tribe(s), their lands, cultures, and their religious beliefs!
"You want, if possible - and there is no more insane "if possible" - to abolish suffering. And we? It really seems that we would rather have it higher and worse than ever. Well-being as you understand it - that is no goal, that seems to us an end, a state that soon makes man ridiculous and contemptible - that makes his destruction desirable. The discipline of suffering, of great suffering - do you not know that only this discipline has created all enhancements of man so far?" Nietzsche
A fourth response:
There’s no such thing as evil. What we perceive as evil is just the workings of nature. Things happen for reasons, but those reasons might be over our heads. The life or death of a single organism is of little significance.
There is no afterlife. Time is an illusion. We are in heaven right now. The sense of existence as a separate individual in a body is an illusion. We are not our bodies. Our true essence in Ultimate Reality is conscious awareness itself.
When I first saw the headline, I comically thought "I usually tell my ex I'll see her in court." But the. I saw you had a deeper intent.
The one thing I do to help prevent the spread of evil is speak up when I can to put a stop to it. I teach my child what the evil is and advise him to act in positive ways. There's always going to be some sort of suffering, treat everyone respectfully but stand up for whats truely right.
Of the three, I would choose the second response. However, I would not say that suffering has a purpose. It's just part of life. Humans suffer. Other animals suffer. Without suffering, would we recognize joy?
