Do you have any thoughts or opinions about whether it's "okay" to lay curses on objects or people?
Everyone’s version of witchcraft is different.
The “threefold law” is not a constant, and does not apply to witches who aren’t Wiccan.
*I* personally think that cursing or hexing objects or people is an acceptable magical practice. I don’t do it very often, but if I think someone absolutely deserves to be hexed, I will do so. Generally, my curses run along the lines of “You will get what you deserve, The Universe knows what you have done, your actions will turn against you”.
