Lincoln and the Barto - The Littering Joke

i sometimes feel like i get more bent out of shape about littering than i do mass murder and i really understand why that is but i guess it's that little thing phenomenon. In lincoln in the barto there is this section that is really kind of amazing where all these spirits are talking about that they did what they did because of the circumstances they were raised in. It raises this again back to this deep sort of not knowing right you know how do you judge people on their actions recognizing that we don't all have the same capacities?
