Exactly. It may seem harsh, but judgement is loving. During the times of Noah the earth was dominated by evil and not just evil but pure evil. It was basically hell on earth. It had to be destroyed.
The times of Noah (pre-flood era described in Genesis 6) are portrayed in the Bible as one of the most profoundly evil periods in human history—so extreme that it prompted God to judge the entire world with a global flood, sparing only Noah and his family.
Genesis 6:5 — “The Lord saw how great the wickedness of the human race had become on the earth, and that every inclination of the thoughts of the human heart was only evil all the time” (or “every intent of the thoughts of his heart was only evil continually”).
The earth was “filled with violence” — suggesting widespread aggression, injustice, murder, and chaos (echoing earlier sins like Cain’s murder but on a global scale).
Some interpretations link part of the evil to the “sons of God” taking “daughters of men” as wives, producing the Nephilim (giants or “mighty men of renown,” Genesis 6:4). Views differ
Jesus referenced this era in the New Testament (Matthew 24:37-39; Luke 17:26-27) as a time when people were so immersed in normal life (“eating, drinking, marrying”) that they ignored warnings of judgment—showing total apathy toward God amid the evil. Noah is called a “preacher of righteousness” (2 Peter 2:5), implying he warned for years, but virtually no one repented.
In summary: The evil wasn’t just “bad” or occasional sin—it was maximal, pervasive, and uninterrupted. Every thought, every heart inclination, every way of life was oriented toward evil continually, with violence saturating society. The Bible presents this as so severe that nothing short of a complete reset (the flood) could address it, while preserving one righteous family to start anew. This serves as a stark warning about unchecked human sinfulness and God’s holy response to it.
