Shredder seems a bit TOO obsessed with destroying Splinter.

Let's hope not. Utrom Shredder wasn't neccesarily seen as someone that wanted to take over the world at first either. Later seasons developed that more and more. Let's hope season 2 or 3 doesn't pull a 'now that Splinter and the Turtles are dead, we can take over the world' or a 'with this Kraang technology, we can take over the world' or maybe even a 'if we team up with the Kraang and make a Technodrome we can take over the world'.
