There was the teenage girl just a few weeks ago found guilt after talking her boyfriend into committing suicide.
I would think in any case it would come to intent. In the case of the fly, there may be some leniency. The intent was to help. Similar case were someone pulled a gun on a cop and a bystander pulled his firarm. Pulled off three shots. Two hit the bad guy, one hit the cop in the shoulder. No charges filed based on intent to assist in the support of life.
One meant to help and did, one meant to hurt and did. I would assume intent would be the strongest ruler
