A sickness has infiltrated the minds of the masses. I imagine most who have caused harm did not start out in life to do so. No ~ circumstances breed a warping of the mind and misunderstandings and blame cause guilt and shame.
The only care for it is awareness and conscious effort to improve thought and action. Trying to be nice is an every moment thing. Choosing thoughts and words are so important. The flippant burst of harsh verbiage can cause damage for a lifetime.
Energy accompanies thought, so even when not spoken it is still felt, sensed. There are more who are listening than perhaps many are aware.
