John Gill, on Prov 21:10

“The soul of the wicked desireth evil, he will not have pity on his neighbour.”

“The soul of the wicked desireth evil,.... The evil of sin, it being natural to him; he chooses it, delights in it, craves after it, under a notion of pleasure or profit: or the evil of mischief; it is a sport and pastime to him to do injury to others; see Pro 10:23; he desires both the one and the other with all his soul; his heart is in it, he is set upon it, which shows him to be a wicked man; his neighbour findeth no favour in his eyes; not only he delights to do mischief to an enemy or a stranger, but even to a neighbour and friend; he will do him no kindness, though he asks it of him; he will show him no mercy, though an object of it; he will spare him not, but do him an injury, if he attempts to hinder or dissuade him from doing mischief, or reproves him for it.”
