First off, RBMK (Chernobyl) wasn’t safe as designed. In the US, the style of reactor wouldn’t have made it through the required licensing.
Second of all, the consequences being way worse is an exaggeration. If a nuclear power plant has a small release, the (real, scientific) impact would be minimal. If it has a large release then something else happened and the reactor containment was destroyed and whatever massive natural disaster did that is causing waaaaayy more problems. We’re probably all dead anyway.
People are afraid of radiation because you can’t see or smell or hear it. Which is probably a good thing considering you are surrounded by it all the time.
Someone recently said to me that if people had been introduced to electricity by watching someone die in an electric chair, they’d refuse to have power in their homes. People were introduced to radiation by an atomic bomb.
