Perhaps you've heard Alanis Morissette's song lyrics on a radio station:
"You, you, you oughta know!"
If we're indignant at the folly of another we may desire to yell out much the same.
However, risk is engendered if we speak angrily towards another (mayhaps to all but people who've become unperturbable like Christ is).
Therefore howsoever upset we become, if so, we should strive to never tempt another to sin against anyone nor indulge in sin personally.
