Taking attendance (something I am positive they are NOT doing) doesn't matter. Part of Attending BYU is going to Church each week (within reason). If you choose not to, you are choosing to have you EE revoked. If you choose to break the honor code, you are choosing to put yourself at risk of being reported.
This isn't the Bishop's fault. This isn't your roommate's fault. YOU are free to choose. Once you choose, you have generally also chosen your consequences.
