Why Marry? Because you'd get to be the Queen, with a capital Q.
Why F***? Because he definitely inherited the Lannister looks and hopefully inherited the family's bedroom skills as well.
Why Kill? Because he is clearly not the nicest king to have ever taken the throne. And he is a little too quick to the greatsword.
Why Marry? Because he is very driven when it comes to his goals. And that brooding, handsome face wouldn't be the worst thing to come home to day after day.
Why F***? Because he has lots of bedroom experience and many of his conquests come back for seconds.
Why Kill? Because he seems to have no trouble destroying anything - or anyone - that gets in the way of his plans.
