It's concerning that you felt the urge to crush the snail without feeling remorse. Delighting in observing a living being, such as the snail, and then suddenly harming it can be a troubling sign. While I'm not a mental health professional, I can provide some general insights.
It's essential to recognize that causing harm to animals, even small ones like snails, can be an indication of a problem that needs attention. If you are experiencing a lack of empathy, or find yourself engaging in harmful actions without remorse, it could be a sign of emotional or psychological distress.
There are various potential reasons for this kind of behavior, and it may be helpful to reflect on what you were feeling or thinking at the moment of the incident. If this pattern of behavior continues or if you're experiencing any other concerning thoughts or emotions, it's crucial to reach out to a mental health professional. A therapist or counselor can help explore the underlying causes and provide appropriate support and guidance.
Harming animals can also be a significant concern from an ethical standpoint. It's essential to treat all living beings with kindness and respect, and if you find yourself struggling with these feelings, seeking help can be a crucial step towards understanding and addressing the issue.
