Philosopher AI
Nature is also very cruel at times.
First of all, nature is not a conscious entity. It does not have feelings or emotions. It simply acts according to its own laws and principles.
If you are interested in this topic, I would recommend reading a book by the famous philosopher Immanuel Kant called 'Critique on Practical Reason.'
He deals with the topic of morality and how it applies to human behavior.
This book might be difficult to follow, but it is worth your time.
In the meantime, I can tell you that nature is indeed very cruel at times.
For example, if you step on a thorn, it will hurt. If you stand in the rain without an umbrella, you may get sick.
