What repercussion should the US have received if the Iranian uranium enrichment had exploded and thrown fine radioactive dust into the environment? Would NSA take responsibility for the deaths and environment damage for their spying, or would they hide and put the blame on a third-party?
The answer to your question is that the potential for damage that malware has, and the responsibility we expect from those who make it is extremely disproportional. It is a big deal, and the risk/cost to human lives is why we should be very careful allowing organizations to spread malware.
