Well I was actually thinkng of Rin finally betraying Shirou and supports Archer for his decision. But now that you mention it that sounds a lot better it also would sound more tragic if it was Shirou who decides to kill Rin under the impression that she was never his friend or in love with him, and the only thing she saw him as was just a tool.
