For me Grishka, it was the bit where he said he shouldn't be pardoned.

The reason he (Hastings) gave cannot possibly be summarized as

Alan Turing deserved his punishment

As I read it, the idea seems to be rather that Cameron does not deserve to pardon such a hero. Not quite wrong in my opinion, although worshiping heroes / martyrs is questionable as well - it implies appropriating them for one's own agenda.
