Why Rabbi Akiva Cried

The Talmud says that when Rabbi Akiva would study the Torah, when he got to this verse, Rabbi Akiva would cry. Why would Rabbi Akiva cry? Rabbi Akiva said to himself, well, if the Torah says you need an atonement when you wanted to do an aveira and you didn't even do the aveira properly, you didn't even do an aveira, and the Torah says you need an atonement. This is where the thumb goes up, gentlemen. So, kal vachomer, all the more so if a person intended to do an aveira and did an aveira, all the more so you need an atonement. That's where Rabbi Akiva would cry. The the the magnitude of responsibility that we carry for doing an aveira, you need an atonement when you didn't even successfully do an aveira, so certainly you need an atonement when you do successfully do an aveira. That's where Rabbi Akiva would cry.
