Is Pharaoh evil?

They say that Pharaoh was a wicked, evil man who made the people of Israel slaves, etc., etc.
On Saturday, the token fell to me, that maybe he's not really evil. What's the story? He sees that a foreign and outside people are growing stronger and multiplying in his land.
He only sees danger to his country and his people! He is not evil, he is simply a politician. He is king over a country in danger, so he takes responsibility and does what is necessary. He is like today's Zemmour. But not evil.
In the time he lived, it wasn't necessarily bad to enslave people. He did as others would have done.
In short, why is he described as evil?
