Yes, but I optimize death-bed regret at this point, when I am alive. Let's say I regret how I behaved to a certain person in the past. When I wholeheartedly apologize and truly regret it, I see the death-bed regret be lower for all days afterwards.

It's like via-negativa for hapinnes [1]: being more happy by removing things that makes me unhappy.
