I don't see what the problem is. He didn't obey her order, he broke the law... Should she be merciful in any occasion? And I don't even like her that much...

Indeed she did! First of all... If she absolutely had to punish him for what he did why do it publicly where everyone loves him??? So stupid... Would she expect them to understand the situation?

Then second like he said she is the law now... There is no "The law" you can make your own choices! and there won't come anything good out of punishing him! He was very loyal to her and death is very extreme too... maybe she could punish him a bit less extreme? Of course he did something wrong but forgiveness is very important.

And how she coldly ignored him when he said "Mhysa" and "Forgive me please... Dany is just going to far with all of her judgement! First the masters being brutally hanged and now this!... She will never be a good choice for one to sit on the iron throne! She has too many things she still needs to learn.

Margaery would be a million times better at being queen! I also think, Robb, Renly, Tommen and Stannis was/is a better ruler

When that is all said I still like Dany... I'm just disappointed of her decisions

Her reasons were honorable but the outcome was profound the second she announced it.
