Also, Goku revealed that he was not truly tired, he wanted Gohan to observe Cell's techniques. Every point you all make about Goku being a bad father has been fathered. Vegeta, on the other hand punched his own son Mirai Trunks in the stomach when he tried to warn him about the cyborgs & punched Chibi Trunks superhard in the face. Has Goku ever done something like that to his son? Not at all.
