Suffering

Most will either figure out some way to justify their suffering or the suffering of others as a good thing or that of a deserved punishment of some sort.

Even if there is no recognizable reason for you or others being punished or even deserving it, somehow you will often be content with the idea that their suffering may be punishment for actions of the past.

Even the actions of the past seem a better answer then accepting any responsibility for the perceived ill-fated human condition.

Even among those that accept, without judgment, the law of cause and effect as the reason for any action or event, however pleasant or unpleasant, most will equate responsibility with the idea of a universal karma that involves a equal or even greater payback to occur for causing suffering in the world, and likewise for causing good in the world.

Even when no foreseeable act of ill will can be found to justify the degree of suffering being experienced, rather than looking inward for the answers many will blame past lives or events earlier in life that you don't remember.
