''This was second rank of the worst for me. They had to make Merlin was responsible for the death of Uther. Morgana enchanted the necklace, but Uther died in Merlin's hand. And the worst part, they made it that Arthur didn't even know that Merlin or Dragoon was innocent. This is second worst to me cause Uther directly died in his hand.''

The problem there was that Merlin sought to use Uther's life as a bargaining chip, and apparently had very little faith in Arthur softening towards magic, despite his willingness to allow it to be used to save his father's life.

Had he had Gaius tell Arthur that, if he was sincere about wanting to allow magic to be used to save Uther, he should stay in his chambers by himself for a couple of hours, instruct the knights to do the same, and swear not to ask any questions if his father was better when he next saw him - much the same as Uther did when he wanted magic used to save Morgana - Uther would have been healed before Morgana or Agravaine could do a thing to stop it. The time he spent orchestrating an elaborate ruse with Dragoon and obtaining promises from Arthur about the way those with magic would be treated, rather than having faith that it would at least give him serious food for thought on the subject, gave Agravaine time to update Morgana and obtain the pendant that would keep Merlin from healing Uther.
