When Splinter told Karai the whole story about his and Shredder's rivalry, I had no idea it went deeper then over Tang Shen.

The Hamato and Foot Clans had been enemies for centeries. Shredder was just a child then. He had no idea what was going on.

Splinter's father took pitty on him and took him in as a Hamato ninja where he and Splinter became friends and rivals until Tang Shen came into thier lives and Shredder learned the truth about himself and his Foot heritage.
