* Backwards poems are a literary device: They're designed to be intriguing and sometimes humorous. The backwardness itself is the point, and it's not meant to be taken literally or interpreted as a message.
* The human brain is adaptable: We can easily recognize patterns and understand language, even when it's presented in unusual ways. Backwards poems might be confusing at first, but they don't contain anything inherently harmful or likely to cause mental instability.
* "Crazy" is a subjective term: It's important to avoid using it in a way that suggests mental illness. People react to things differently, and what one person finds bizarre or unsettling, another might find intriguing or even amusing.
If you're concerned about someone's mental health, it's best to reach out to a professional who can offer support and guidance.
