Mishnayos Sanhedrin Perek 8 Mishnah 5

A stubborn and rebellious son is sentenced to death not because of the severity of the transgression that he already committed but on account of his ultimate end, because a boy of his nature will grow up to lead an immoral life, and it is better that he should die while he is still innocent, before causing excessive harm, and not die after he becomes guilty. This is because the death of the wicked is beneficial to them, because they can no longer sin, and it is also beneficial to the world, which is now rid of those who do it harm. Conversely, the death of the righteous is detrimental to them, as they can no longer engage in the performance of mitzvot, and it is also detrimental to the world, as the righteous are now absent from it. By way of association, the mishna continues: The wine and sleep of the wicked are beneficial to them and beneficial to the world, as when they are sleeping or under the influence of wine, they do not cause harm to others. And, conversely, the wine and sleep of the righteous are detrimental to them and detrimental to the world, as wine and sleep prevent them from engaging in their good deeds. The dispersal of the wicked, so that they are not found in close proximity to each other, is beneficial to them, as they are less likely to provoke each other to sin, and it is beneficial to the world. The dispersal of the righteous is detrimental to them and detrimental to the world. The assembly of the wicked in one place is detrimental to them and detrimental to the world, while the assembly of the righteous is beneficial to them and beneficial to the world. The tranquility of the wicked is detrimental to them and detrimental to the world, while the tranquility of the righteous is beneficial to them and beneficial to the world.
