should i feel bad?

You should feel bad about feeling bad. Save your guilt and pity for things worthy of guilt and pity -- basically anything other than a chess game.

No. It would be the same as asking if your opponent should feel bad capturing your knight with his rook (that you overlooked) ? So don't feel bad in that situation - fell lucky instead.

Lee, mate, that was just downright mean of you. Haven't you got any conscience at all? And please wipe that smile off your face.

Don't believe him, LeeTaylor85! There's no proof of that. In fact, Jesus probably only says stuff like that because he knows his daddy will give him a divine whipping if he ever says anything "unbecoming of a demigod."
I imagine having God for a dad can be rough, even beyond being forced to pretend to love people you don't. Imagine being forced to listen to boring prayers, not being allowed to cut your hair or shave your beard, not being allowed to wear anything but a robe...
