Proverbs 21:12 The Righteous One takes note of the house of the wicked and brings the wicked to ruin.
Righteous people may well be able to spot unrighteous people, and the other way round; but without full judicial process, we do not have any rights to bring them down.
We live in a world which is supposed to be governed by laws. If we go about breaking the law to uphold what we think should be upheld, then we are nothing more than them.
Allow God to bring the people who work against Him to justice and show them Jesus’ ways instead.
