Here's why:
* Card Destruction vs. Life Point Loss: In Yu-Gi-Oh!, card destruction and life point loss are separate actions. Many cards have effects that destroy cards, but they don't necessarily inflict life point damage.
* Life Points and Damage: Life points are your health in the game. You lose them when you are attacked by monsters or by certain card effects that directly inflict damage.
* Examples:
* "Raigeki": This card destroys all monsters on the field, but it doesn't cause life point loss.
* "Dark Hole": This card destroys all monsters on the field, but it doesn't cause life point loss.
* "Torrential Tribute": This card destroys all monsters on the field, but it doesn't cause life point loss.
Important Note: While destroying a card doesn't directly impact your life points, some cards may have effects that trigger when a card is destroyed. These effects might cause you to lose life points, but this is a result of the specific card effect, not the destruction itself.
