Was prophet Muhammad really merciful when he married the widow of the man whom he tortured and killed?

Question

There is a story in Islamic history books. Muslims usually quote that story to prove how prophet Muhammad was really merciful. The story tells that prophet Muhammed raided a Jewish village (Khaybar) and captured one of its leaders (with the name Kynana Ibn AL Rabie). Prophet Muhammed then TORTURED that man and KILLED him. On the same day, prophet Muhammed proposed the widow of that man for marriage and they wedded the next day (one day after her late husband was KILLED).

Muslims say that the above story is a proof for prophet Muhammad's mercy. I can not see much mercy in that.

Am I wrong?
