Heartwarming / The Elder Scrolls III: Morrowind

• Darius gets one by deciding not to seize Widow Vabdas' land, after discovering her husband was murdered by an unruly Legion soldier and even opens a charity fund to help her in her time of need. And what's more? You can contribute to it!

• Whenever you come across a friendly Guar or Scrib in the wilderness, just to show that not everything is out for your blood.
  • It also says something when a creature visits your sleep and you're Properly Paranoid when the "Your rest is interrupted" message is displayed on the screen...and it's just a harmless little Scrib, tapping the ground with its tail and crawling around. Perhaps it saw you were alone, and went by to keep you company, or protect you from anything else that would have attacked you if they woke you up. Or maybe it was scared and went to you for protection. It just goes to show that even in a harsh alien environment like Vvardenfell, and even if you're a deranged psychopath that wiped out an entire town's worth of people, you can still find companionship where you'd least expect it.
• After you complete the Sixth House Base quest and get infected with corprus disease Caius lets you know he was worried this might happen and found out that the best hope for a cure would be to go see Divayth Fyr. So, to make sure you can get in Fyr's good graces, Caius gives you a Dwemer artifact to give to him, and 1,000 gold along with it for additional expenses. Dwemer artifacts are classified as property of the Empire, and refusing to hand them over is a serious crime, but Caius doesn't care at all.

  Caius Cosades: Yes, I know it's treason to trade in Dwemer artifacts, but don't worry about it. I'm a big-shot Imperial Spymaster, remember? And, yes, it's worth a fortune. But you're worth it. The cash is for expenses, and just in case. Good luck."

• Despite technically being the Big Bad of Bloodmoon, Hircine is actually pretty honorable: namely, he has you just fight his aspect so you'll actually have a fair chance, and when you beat that he just leaves you unharmed and doesn't try to get revenge.
• While slavery is legal and protected in Morrowind, the player has many opportunities to free slaves from their bonds so that they can make a break for freedom. Some quests specifically involve leading endangered slaves to safety, allowing the Twin Lamps to help them return to their homes.
• Several quests for the Tribunal Temple involve healing those normally looked down on by the Temple, including a Sheogorath worshiper and an Ashlander.
• The apprentice wise woman of the Ahemmusa Ashlanders admits to sneaking food and water to an escaped slave that her tribe's warriors captured, later freeing him when she overhears the warriors planning on killing him. She was also apparently quite captivated by his tales of his homeland, and was very tempted to join him to see it for herself.
