It doesn't feel like that to me. In Witchcraft there's the Vow do as you will but harm no one!
For me it seems that any time someone, even yourself, tells you not to do something it becomes a dare.
I tell myself I will try to do no harm.
You're not rationalizing enough. Cause there to be zero harm, and you can play theoretical reductions in harm against your harmful actions.
Are you a doctor?
