I really can't see a scenario where the jury don't find him guilty. They really don't have a choice, they have to uphold the law as it is written. It is not within the remit of a trial to make new law.
No matter the ethical considerations he did kill someone. The law is very clear that murder is not acceptable even if you personally think it's justifiable.
