We cannot doubt something, that anyone who does evil, whose heart is far from being kind, will come to an end, because we have a God in heaven who is watching everything.
The reward of these bad people is not very far, people like that are impious, cold and do not think about committing any act, this happens because their heart is full of evil and in their life only the enemy reigns.
All those who commit such an act, these are abominable before the almighty God, these God considers them impious, and that is why in the book of proverbs the wise Solomon said the following:
20 They that are of a froward heart are abomination to the Lord: but such as are upright in their way are his delight.
21 Though hand join in hand, the wicked shall not be unpunished: but the seed of the righteous shall be delivered.
Proverbs 11:20-21 (KJV)
Here we clearly see that people who walk in the perfect way are pleasant before God, however, those who are wicked in heart are abomination before our God.
What makes a man with a perfect path? He walks in righteousness, obeys God and does His will, he always lives attentive to what the Lord says. But the wicked and crooked man does things that are very abominable before God.
The bad man will very soon receive his reward, sooner or later, but the day will come when he receives the just payment for the evil deeds he did on this earth. But those who do justice, these will be delivered in difficult times and will receive a great reward that great day when we will be all judged for our works.
