I was recently re-reading the ending of Words of Radiance, particularly the scene where Dalinar speaks his first/second ideals, thus becoming a bondsmith. However, he joined with the Stormfather, who was against this, and reacted angrily upon Dalinar's speaking the First Ideal.
While I was reading, it occurred to me that in the Wheel of Time series, forming a similar bond to create an unwilling Warder was seen by the characters as little better than rape, due to the man's inability to resist the bond.
Essentially, Dalinar has forced an ancient and sentient spren into a mental and magical bonding without it's consent or agreement, forcing said spren to provide him with the ability to control Stormlight, and at the same time, putting the Stormfather's very existence into danger if Dalinar abandons his vows.
In your opinion, was this an immoral action?
