I've heard a lot of reasons to not listen to G-d but yours is a duzzy. Had you read the whole story as to why Yeshua was crucified, it might have made a little more sense. The story starts thousands of years before Yeshua was born, many warnings given no one payed attention just kept on breaking the commandments. Four hundred years G-d turned His back on His people, finally He sent His servant Yeshua first to talk, then to die. If the people had listened, if they hadn't sinned Yeshua would not have died. In ancient times sacrifice by G-d's people was done with the first of crops, first born animals, etc. but now G-d was so angry a human sacrifice was necessary.
