You will live to regret your moral cowardice. Specifically, you'll regret the wrong choices it leads you to make. The guilt you feel now is a warning. Don't stay lazy, or that guilt will eventually be augmented by shame.

All we can do is aim to be better, to aim to be perfect is putting obstacles in your own path for your own smug sense of satisfaction, while the world still burns the same.

Unless you can change the many, including those most intransigent, you have to respect that just changing yourself, is something you only do for yourself. I don't see how its "moral cowardice" for me to own a car so I can ferry around my 84 year old father, so he doesn't have to drive, or to flush my toilet after every time I piss.
