I want to share a little tid bit on Baldr that I think many heathens will find interesting. It's taken from the book Our Troth. It expalins Loki's relationship to Baldr, which I thought to be quite interesting.
"Possibly the worst act associated with Loki is the killing of Baldr. To most satrar, this no doubt seems the worst crime possible, the killing of a god. And Wolf's-father is not even remorseful for this act, as well he should not be.
The Edda does not tell of the time Baldr spent in Jtunheimr, learning their ideas before he came back, determined to undermine the gods. He taught them of peace and became the most beloved of the sir. He spread flowers and the concept of utopia. He was actually talking deities of war into being nice. While it is not known why the others were so gullible, Loki was not fooled. He discovered Peace-freak's weakness to mistletoe, which was hard to find as it is not native to Iceland, and put that knowledge to good use.
Of course, this is not serious. Baldr was not out to destroy the strength of the sir, but his teachings were certainly having that effect. Ragnark would be coming early in the year, and the gods would not have had a chance in Hel. And if Loki had simply spoken out against this divine hippie, no one would have listened. After all, who trusts Loki? They would have tied him down right then to prevent him from harming the Flower-powerful. And his efforts would have come to naught (Warder's note: Snorri's presentation of Baldr as a kind, sweet, peaceful Christ-figure is almost certainly a great distortion of the god's original warrior-character, as discussed in the chapter on Baldr, where the many spiritual implications of this myth are looked at more closely. But when one considers what Snorri seems to have been doing here, the Loki he knew is to be applauded as the force of change who - even in a literary work - shows up to keep the forces of stagnation from weakening sgarr. Of course, no one thanks the guy who rocks the boat! - KHG)."
This is from Our Troth by Stephan Grundy. He has some interestings points as to why Baldr was slain. There always more to a story if you look for it ;)
