Regarding the ice cream. You almost finished a pint. A pint is not that big. If eating almost an entire pint makes you bad... I must be an evil fiend extraordinaire.
I have eaten an entire carton (I think there is at quart of ice cream in most cartons) in one sitting on many occasions. Especially when I can find really good peppermint ice cream at Christmas time.
The cheap paper towel misdeed... ah... that is slightly more egregious but I don't think you have to worry about the po po tracking you down over it.
