John 11:33 When Jesus saw her weeping, and the Jews who had come with her also weeping, he was deeply moved in his spirit and greatly troubled.

For me this is a great place to start the passage. Jesus knows our pain! Jesus knows that death is no fun. Even if a serial killer is put to death, it still is sad. There is still no real closure, it does not bring the ones who he was killed back to life. One of the important themes in Ecclesiastes is that death is the leveler of all things. Good and evil, strong and weak, rich and poor, etc. Death is sad. Now imagine the death of a loved one, someone whose life has been closely intertwined with yours. That person is gone. Death now looks so much more evil. This is the kind of scene that Jesus finds himself in.
