he didnt kill her, he just felt as if he did. she indeed commited suicide so her brother will never be able to forget her and stop suffering.i think she knew how her husband was every char is twisted except the brother bc his love was pure but he was abused by his sister and used by his brother in law.but i hope in the end he can at least enjoy part of his happiness with the man he loves even so the shadow of his sister never leaves.
He did kill her the testament left by the sister was in fact a letter of confession by her brother
His sister and the husband were nasty pieces of work. They made brother suffer for their own pleasure and on top of that the sister was still sleeping with her brother while she was married. Bad thing about it was her husband know and was enjoying it. To me they were pushing the brother to kill his sister.
