hahaha the joke of the millenium. so it means madara implanted his eye on kakashi's left eye which kakashi already got obito's eye implanted. so inside kakashi's left eye got two eyeball hahaha.. if i were madara, i will implant my eye on kakashi's right eye,so that kakashi got two sharingan. if ur stupid ever theory is right, it also means that madara ms eye also got kamui tech . try to read manga 602,from there u can see that madara gave up his right eye to someone(nagato),he got only left eye on manga 602. while kakashi got sharigan on his left eye not on his right.
