A righteous person cares for the life of his animal, yet even the compassion of the wicked is cruel.
Proverbs 12:10 TLV

The heart of righteousness is chesed, loving kindness. If you love God, you will love God's creatures.

This does not mean that a righteous man doesn't harm and kill animals. It only means he doesn't treat the animal cruelly. He doesn't torture, maim, or cause needless suffering.

The wicked, on the other hand, do all kinds of hateful things to all of Creation in the name of "love".
