Like the old proverb goes "The person who dosen't speak out against the wrong is a mute devil"
Forbidding and condemning an evil is just as important as enjoining and condoning the good. The more the world is bereft of such beings then truly we are in great peril and calamities are bound to occur with injustice becoming widespread!
And one should not hesitate to speak out against the wrong and/or the wrongdoer regardless of who he/she/they maybe, even if they be their most beloved companion and/or closest of kin!
