I believe it is universally understood and acknowledged that all men will ever act correctly, unless they have a motive to do otherwise.

You may burn my body to ashes, and scatter them to the winds of heaven; you may drag my soul down to the regions of darkness and despair to be tormented forever; but you will never get me to support a measure which I believe to be wrong, although by doing so I may accomplish that which I believe to be right.

Nothing is more damaging to you than to do something that you believe is wrong.

Believing everybody is dangerous, but believing nobody is more dangerous.
