These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Dick Reed, the Serial Killer/rapist in "Re-Do", is a thoroughly misogynist Smug Snake ("She lies. They all lie, " regarding the victim who escaped and got him caught) who gets his conviction overturned because a lab tech screwed up the protocols. He shows zero remorse and no redeemable qualities and finally attempts to perform his usual MO on Erin Reagan, the ADA who convicted him. This backfires fatally. Toby Leonard Moore's performance is so good that it's also the show's first major dose of Nightmare Fuel.
Yuri Denko, an arms dealer whom Erin prosecutes in "Working Girls", is a cold-blooded sadist who has no problem executing a man's wife in front of him in their living room over a business dispute. He then threatens the man's children in a courtroom outburst to scare him into not testifying, then has him killed after the threats scare him into running. He puts out a hit on the surviving witness, hounding her mercilessly, and went after her grandma back in Russia, too (the FSB got there first and protected her).
