This question is unrelated to Buddhism but related to the laws of your land.
I recommend to write to the Court Clerk exactly what you wrote here. They will probably regard you as unfit or too sensitive for jury duty.
I feel conflicted. If I vote guilty, and the defendant is not, i would

Dhammapada
Monks, even if bandits were to carve you up savagely, limb by limb, with a two-handled saw, he among you who let his heart get angered
even at that would not be doing my bidding. Even then you should train
yourselves: 'Our minds will be unaffected and we will say no evil
words. We will remain sympathetic, with a mind of good will, and with
no inner hate. We will keep pervading these people with an awareness
imbued with good will and, beginning with them, we will keep pervading
the all-encompassing world with an awareness imbued with good will —
abundant, expansive, immeasurable, free from hostility, free from ill
will.' That's how you should train yourselves.

Who knows the difference between them except a Realized One?

I (The Buddha), or someone like me, may pass judgment on people.
