Sish hasn't even done the torture you suggested yet! She should at least show the mercy Jedi are so fond of!

The mercy involved would be removing the unicorns. And Sish would kill the unicorns later. Innocent animal lives outweigh not-innocent Sish life who will continue killing and torturing without the unicorns there to paralyze him. So the unicorns stay: it's the Jedi way!
