Is dexter more merciful on female killers

Not implying anything but for example ok I dint count mike donovan

But on zoey Kruger he was calm and also listened to her and chatted a bit

Why did u do that to them?

While on Emmett meridian he didn't let him speak

On Miguel he was sadistic U know that open mouth smirk ,Telling him to shush .

But the reason i mostly said that

On cole harmon he was way too emotional LOOK THE LIVES U DESTROYED and finally on Jonathan farrow he didn't let him speak and that led him killing an innocent man

Though on arthur Mitchell he had killed 200 women but he wasn't enraged he had smth like respect to the elders and played his favorite song
