To understand what you're trying to convey, could you please clarify what you mean by "your bad"?
For example, are you trying to say:
* "I want your evil" (referring to a negative characteristic or force)?
* "I want your misfortune" (wishing harm upon someone)?
* "I want what you have" (but in a negative way)?
* "I want you to be bad" (in a playful or suggestive way)?
Once you provide more context, I can give you a more accurate French translation.
