Their eyes certainly were opened when they bit from the fruit, but not in a good way, at all. They experienced shame, realizing they were naked and trying to cover themselves. They experienced fear, realizing they had disobeyed God, and trying to hide from him when he entered the garden. Just in the same way as children hide from their parents when they fear punishment.
So God preferred it when Adam and Eve were naked? Sounds kinda pervy to me

Is being a servant carrying out the demands of others an inherently bad thing? God is the perfect master; he did not abuse or mistreat Adam and Eve, nor was he unfair with them. He gave them everything they needed, and he cared for them lovingly; even after they rebelled against him, he still cared for them, providing clothing for them before he cast them out of the garden. Likewise, he does not treat us unfairly now. We deserve every punishment he has taken on us; none of us are innocent before him. It makes me all the more thankful for what Jesus did when he paid the price for my sin.
So I deserve a punishment for what people I don't even know existed did? I'm starting to see your logic towards all non-Christians.
"Muslims did 9/11! Let's punish them all!"
"2 random people who represent everyone else sinned against our god! We all deserve whatever horrible punishments we get from our vengeful god!"
