A foolish man is one who thinks to do evil, who only thinks and speaks in his own opinion, the one who is always walking under his same thoughts, and everything he does seems right to him.
In Proverbs 14:12 we can find this quote that says the following:
There is a way which seemeth right unto a man,
but the end thereof are the ways of death.
This is clear that people who practice such thing with other people who suffer from the evil of another, but God who looks at everything around them and has control of everything helps the righteous and and protects him from the evil one and from all those who do evil.
One day will come the reward of all who do iniquity, those who make suffer and mistreat anyone who seeks the faith of the Lord, one day they will fall from their own feet and die, because their evil came before the presence of God.
The lips of fools bring them strife,
and their mouths invite a beating.
We know that everyone who speaks a lie provokes disputes and causes other people to fight among themselves, looking for the way that everyone disagrees. They remain in controversies and disputes.
The mouths of fools are their undoing,
and their lips are a snare to their very lives.
The fool believes that everything he is doing is fine with his point of view, but we know that it is not so, since there will come a time when that will end, all his thoughts of evil will be diverted and fall on themselves.
Many of us know the lie and we know that evil can not be done, but around us we have people looking for ways to divert others to practice everything that God does not like, being so that everyone who joins these facts and does not depart from evil, this will also receive his reward, and this will happen for to have accepted, to follow the path of perdition and evil.
