more complicted than that.
he, or at least AC PIRA, ordered bombs to be detonated in English towns to 'spread the pain' outside London. the concept of operations was to have warning phone calls to reduce collateral damage, but not to give the police too much time so that there was no real fear. the ideal result being lots of economic damage, quite a bit of fear/panic/close shaves and the police being run off their feet - but if no one was killed, or very few people were killed (in these attacks on economic targets rather than the intentionally lethal attacks on military/political targets), then PIRA wouldn't lose any sleep.
the trick was to give warnings that would be resonably effective, but not so generous so that there was no panic in the effort to clear the area. sometimes they got that right, sometimes they did not. it is however fundamental to understanding PIRA bombing campaigns to grsp that PIRA was targetting a concept - the carefree saturday afternoon at the shops - far more than it targetted individuals.
anyone who disputes that mass casualties were not PIRA's intention in every attack they made ought to ask themselves why PIRA gave warnings in the first place.
