I would consider my character a good guy. Does the right thing.. a paladin of sorts if you will. Anyway, he is prone to his bad moments I guess.. but I am only really bad to people I consider evil.

Anyway, I went into a bandit cave somewhere and found 4 bandits sitting in there. I murdered 3 of them by giving them some good bashings with the dwarven mace. Then I the final bandit.. a female imperial or nord.. I really can't tell them apart. Anyway, I end up crippling her in the fight and she falls to the ground and begins crawling while saying "please, you bested me! Have mercy!" Now.. my paladin shows no mercy for evil people... so I cranked back my arm with the mace in it for a standing power attack and club her over the head. and her now lifeless body slumped down to the ground.

Finally.. I strip her down of all her gear and clothing, then I strip down of all my gear and clothing. Then i throw her body in the fire/ hearth thing that was there and I have some nice cabbage soup.

what a day.

Don't feel bad about it. Every hostile enemy that's "surrendered" to me and I've sheathed my blade for has always just gotten back up and vainly tried to kill me. I'll still keep trying, but I think they all just want to die.

how do you pick people up ... and throw them in the fire?

Don't feel too bad. What I did for the Mace of Molag Bal puts that to shame. Besides, my character takes no prisoners.

Hmmnn.. of the top of my head

Chopped the head of 5 witches in a Coven. Slashed the throat of a fleeing woman in an alleyway, to fufill a Dark Brotherhood contract. Tore apart an innocent townsperson to feed my Werewolf bloodlust. Oh and also killed a Priest of Mara to gain a Daedric Artifact.
Then there is the countless enemies i have decapitated with my trusty greatsword. I`d say most of my time spent in the world of Skyrim has been gruesome

Deep in the forest I found Cottage, I went inside and found the two floors infested with Bandits. I killed them and started perusing their liberated belongings, only.... they were still owned by someone. Confused on this Mystery, I explored the basemant of the house wondering where the body of the owner was when I found a most curious thing, a button hidden by a bookshelf. "What the heck? Buttons don't exist in a fantasy game?" Naturally, I do what everyone else would do, I pressed the button. The bookshelf turned out to be a secret door, a secret message falls to the ground from where it was held up by a dagger speaking of TREASURE and consequences for DOUBLE DEALINGS. I eventually find the boss who's "strong arm" failed miserably against my magical shield followed by a shield bashing beating that her soul would never forget. I clear out rest of the rather long and slightly less linear Secret Bandit Hideout, find some phat lewts, but... I also find a family of murder Kajhits. Being a Kajhit myself, I go on a post murderous Rampage. First I take the bodies of the murdered family and put them side by side in the Ancient Nord Tomb, then I take all the enemy bodies and throw them down a pit that had spikes on the bottom where I teabagged the bodies on top in Traditional gamer fashion. Feeling Vindicated I left the Cottage just as the sun came up and went on my merry way.

Walking into Solitude and watching an execution.
First time I watched it, second time I interupted with a swing of my ancient nord sword. That didn't work out to well.
Watching my Nord get his head chopped off is probably the most gruesome thing, maybe because it happened to me.

The Assassin induction quest where you need to kill the woman at the orphanage, Walked in and sliced her head off (Literally, Decapitation) in front of all the children. I probably scarred them for life...

When you hold down your interact button it attempts to grab that item. For example on PC it is E, so when I look at a corpse and hold E instead of looting I grab whatever part of the body I am looking at and you can move them around. During a certain quest you crash a party I would move the bodies into other rooms to prevent the other guys from seeing them.
