Dragon Ball Z's Goku is a good Dad, no matter what people say:
take this confidence a bit far, factoring into one of his weaker moments as a dad — giving Cell a Senzu bean and putting Gohan into the ring with him. This is often cited as one of the biggest examples of Goku being a bad dad and I can’t disagree., it comes from Goku’s sincere confidence and recognition of his son’s power, and more importantly, Goku realizes his mistake and was, before Gohan proves that his dad was right to believe in him, unleashing the power of an ascended Super Saiyan.
In the Cell Saga, Goku teaches Gohan how to turn Super Saiyan, how to perfect the form and how to maintain it. Here, we find that Goku is an excellent teacher, a difficult task especially when your student is also your son, and I think it speaks to Goku’s ability as a father that he can balance the two. Goku is patient, kind, encouraging and understanding — every time Gohan struggles or stumbles, Goku tells him that not even he or Vegeta were able to master the transformation in a day.
