But suffering isn't all bad.
Suffering does tend to build character in people. Most of those we call "heros" are people that have gone through tremendous struggle in their lives. Their trials and tribulations serve to inspire and give hope to others. Life's most important lessons don't come easy.
If there is a god, and people do indeed go on after death; then is a brief instant of suffering that bad compared to an eternity of bliss? Maybe this life and its trials are nothing more than the pain a child goes through during the birthing process. It seems traumatic, but where would we be without it?
