A subtle reason for apathy is that justice rarely has much to do with our lives. Unless we've personally been victims of injustice, we can take for granted that life is generally fair.

We may not choose apathy, but when we choose anything other than love and empathetic justice, we get apathy by default.

Apathy is sustainable only as long as injustice doesn't harm us--and we don't care that it's harming others. Apathy lasts only until injustice knocks on our door, and we're forced to look into its eyes.

Thou shalt not be a victim. Thou shalt not be a perpetrator. Above all, thou shalt not be a bystander. (U.S. Holocaust Memorial Museum qtd. in Halter)

At the end of the day--of almost any day, regardless of what we have done or left undone--apathy tells us that it's perfectly acceptable to live with illusions of our own justice.
