It’s downright laudable to “steal” from major corpos. Whether it’s ethical to steal from a mom and pop shop is an “it depends” kind of situation. (I definitely know of small local businesses in my area that are run by absolute shit-bags.) And punishment isn’t the right way for society to deal with antisocial behaviors among its inhabitants. (Not that stealing (particularly by a pro-capitalist’s definition) is necessarily “antisocial”.)
