Let’s give Dick a nagging mother. When Dick’s point of change occurs and he finally stands up to her, she may not have a similar epiphany. She may continue to nag as he walks off. However, over time she will shut up or find another audience. People only do what works. When a method stops working, they have to find new ways to achieve their payoff.
The same is true if Dick is fighting off vampires. He will have to gain the right knowledge or the right weapon. This will inspire respect in some, resentment in others. Not everyone will be happy when your hero becomes heroic. Some might try to tear him down or trip him up. That’s where foes come in. Foes don’t have to be henchmen of the antagonist. They can be people your hero once thought of as friends, or at least benign acquaintances. Even good friends might be mildly inconvenienced or outright threatened by this change.
