Tell that to the millions dead. Sorry, it was an accident. Whoopsie daisy. We found the person responsible and we just pat him on the back and gave him icecreamSu'Kal is neither genocidal nor a murderer.
The Burn was an accident. That's all it was. A plain, simple accident. Su'Kal didn't intend for it to happen, it was a purely instinctual, defensive reaction. He had no idea of the destruction his "cry for help" would cause.
If anyone tries to take action against Su'Kal for this...they're the murderers, not him.
