The brother is already dead and in real world, you are free to marry your sister-in-law if she is no longer married to your brother. Its not a taboo relationship as they are not related by blood. In-law relationship ended with death/divorce.

I feel sad that many people in general didn't get the brilliance behind the Emperor's benevolent decisions. He win battles with wit and intelligent but many viewers prefers him to be a ruthless king that take lives. Viewers keep wanting him to take lives but taking one person live will escalate to something even bigger but they failed to see that. Like Guo Jia said, 'A wise ruler is not the one who kill powerful subjects but to work with them to pacify the nation.' And that is what exactly the Emperor did.

They failed to see that many times his kindness save them from enemies' traps and never once he was caught red-handed by the enemies. Everytime when he compromised with his enemies, he got more advantages in return -- just by giving something small, he achieved something bigger in return. He won the hearts of his enemies and supporters and they call him a great and a wise king for a reason. He strike fears in the heart of his enemies just by being kind -- I find it really brilliant how his kindness is the reason why he managed to turn around the weak Han Imperial Family name into something that the people respect and love.
