Yoma 35 Bittul Torah

The Gemora states that a rasha will be asked why he wasnt busy in learning Torah and his answer will be because he was engrossed in his evil inclination. What kind of excuse is that and why would he even attempt that? Reb Leib Chasman answered that he would rather answer this way and not have to admit to the truth that he was not busy in learning. Wow!
