This is like feeling bad after killing some thalmor.
You actually compare the evil, horrible Thalmor to Dragons? Shame on you! LOL
The only time I feel "sorry" for a dragon is when I kill it RIGHT after it had just been resurrected by Alduin. That has got to sting. Dead for hundreds of years, "OMG, I'M ALIVE AGAIN! Oh my god, Skyrim is still so beautiful. This is the world I remember. Oh, how I have missed it so." Then I come in - Fus Ro-dead dragon.
That's pretty much it.
I like fighting dragons. They are one of the hardest beasts to kill in Skyrim. I want that challenge. And it's no secret that I am Dovakhiin. Odavhiing said the dragons knew who I was and what I could do. So if they are cocky enough to want to fight me to the death, bring it on. I'll gladly reward their arrogance with my blade in their throats.
But I'm no bloodthristy killer. Would I entertain the idea of peace-talks with the dragons? Of course! For one, there is no way in HELL that I am going to
. Hell.No. And if one
can change the very nature of dragonkind, then it stands to reason that the other dragons can. If they want to live in peace, they are more than happy to. If they need a translator, for our language into dragon language, I know just the guy living atop the Throat of the World. Surpass the urges of your dragonblood if you want peace. If not, you can die a glorious death at my hand. The choice is theirs. Those who seek peace may have it; those who seek destruction shall receive it tenfold from the watchful protector of Skyrim, ME.
^ This! I like your attitude and totally agree with you there! I do feel bad when I kill a named dragon that has JUST risen! awwww man, too bad!

I've always loved dragons and admire their power, as well as their wisdom. I wish that more dragons could be portrait like Paarthurnax, but alas, I do believe the majority is rather haughty and looks down upon puny mankind. I mean, even with all their wisdom, they ARE still "creatures/animals", who may not share the compassion of men. Oh and I do have to say, I love the rush of adrenaline when fighting a dragon, in self defense of course!

In other Dragon lore it`s not unheard of for a dragon to fall in love with a human and vice versa.
Of course, such things are usually doomed to failure.
Some Dragons are downright evil, some good (in the minority) and some downright misunderstood. Main problem with Dragons is they have a huge ego and find it very hard to empathise with puny Men. It`s like a clash of a high and low culture. Why should Dragons even deign to understand people?
I have a book of Dragons (with nice art too) about all the different Dragon lores and types of Dragon. Many look similar to Skyrim Dragons.
Well, dragon and human... Dovahkiin's dragon blood had to come from somewhere, no? LOL
Speaking of Dragon Lore and Dragon in books, I also have several books on dragons. Plus, my favorite Fantasy book series features some amazing dragons! Check it out when you get a chance. The series is called http://www.kateforsyth.com.au/eileanan.htm! Amazing books!
