So my question is this:
I heard that if you have an intention or you think about doing a Mitzva, then you still get the Mitzva e.g. if you think to yourself that you are going to give Tzedaka later, even if you don't, you still get a Mitzva.
If you are thinking, or intend to do an Aveirah, chas veshalom, do you still get the Aveirah? E.g. if you are thinking about breaking Shabbat, do you still get the punishment as if you actually had??
And does this apply to the 3 cardinal sins (adultery, idoletry, murder)?
