Saul chose his own path and became livid when his honor passed to David which caused him to envy and to attempt to kill him. It was his own nature that caused him to sin and since Saul chose sin he was left to a reprobate mind.

Edit: On to Pharaoh
A man can only use his will within the limits of his nature. So the first point is that Pharoah being unregenerated could only make decisions within his sin nature; free will means that while man canmake any decision, he will only make the decisions that his sin nature allows him to make. (Same applies to Saul)
Exodus 7:13
Yet Pharaoh’s heart became hard and he would not listen to them, just as the Lord had said.
Exodus 7:22
But the Egyptian magicians did the same things by their secret arts, and Pharaoh’s heart became hard; he would not listen to Moses and Aaron, just as the Lord had said.
Exodus 8:15
But when Pharaoh saw that there was relief, he hardened his heart and would not listen to Moses and Aaron, just as the Lord had said.
Exodus 8:32
But this time also Pharaoh hardened his heart and would not let the people go.
Exodus 7:1
Then the Lord said to Moses, “Pharaoh’s heart is unyielding; he refuses to let the people go
Exodus 9:34
When Pharaoh saw that the rain and hail and thunder had stopped, he sinned again: He and his officials hardened their hearts.
Now for the verses you’re referring to
Exodus 10:1
Then the Lord said to Moses, “Go to Pharaoh, for I have hardened his heart and the hearts of his officials so that I may perform these signs of mine among them
Exodus 10:27
But the Lord hardened Pharaoh’s heart, and he was not willing to let them go.
Exodus 14:8
The Lord hardened the heart of Pharaoh king of Egypt, so that he pursued the Israelites, who were marching out boldly.
Exodus 10:20
But the Lord hardened Pharaoh’s heart, and he would not let the Israelites go.
Now, is YAH contradicting himself in these verses? The obvious answer is no when comparing the different verses. Pharaoh hardened his own heart in pride and rebellion because he misunderstood YAH’s mercy as weakness. That’s why every time he wasn’t completely destroyed by each preceding plague his heart became harder. A man’s nature determines his choices and YAH calculated that Pharaohs nature would cause him to harden his heart. Nuance, my boy, nuance. If he just made Pharaoh free the Israelites then there would have truthfully been the absence of free will. You have to have understanding. These men were stiff-necked so YAH let them trap themselves with their own sin, they weren’t forced by any will but their own.
Your move.......
