If you promise or swear to do something evil or sinful, do you have an obligation to fulfill that promise?

If you promise or swear to do something evil or sinful, do you have an obligation to fulfill that promise? I know this is probably a silly question, but it's been bothering me. My main biblical source on this that I could find is Leviticus 5:4–5: "Or if a soul swear, pronouncing with his lips to do evil, or to do good, whatsoever it be that a man shall pronounce with an oath, and it be hid from him; when he knoweth of it, then he shall be guilty in one of these. 5 And it shall be, when he shall be guilty in one of these things, that he shall confess that he hath sinned in that thing:". I think it's implied that you shouldn't fulfill an evil promise either, but I"m not sure. I'd really like some help understanding the verse and with addressing this question.
