[Samurai Jack] Why doesn't Aku fling Jack even farther into the future?

So the original portal of time that Aku opened up looked like it was one of his many superpowers, rather than something he owned. What's stopping him from sending him even farther, if only to buy some more time for himself? Hell what's stopping Aku from sending Jack into the death of the universe?

Aku sent Jack to a place where his own word is law and he can have hundreds of bountry hunters go after jack any time he wanted, he made a good choice. He was probably just thinking in the moment as well considering he opened the portal when he was about to be defeated. And either way, big deal that he's in that time...he could just destroy all the time portals if he wanted.
