I understand where you are coming from. I wanted to be an archaeologist, but the idea of digging up things that I wasn't supposed to, along with other reasons, helped pull me out of that idea.
But I really really doubt that there are real curses. And even if they were, ancient Egyptian priests didn't put them there; construction workers did. But back to really doubting they are real; remember, at the heart of that theme park is show business, and I know that people in that business can be superstitious, so I just really doubt a REAL curse would make it into a ride. And again, some modern guy wearing jeans would have copied it there, without malicious intent at all.
I'm superstitious, but I loved the ride, and if anything, my life has gotten infinitely better since I experienced the attraction! (knock wood) (or, rather, laminate coffee table from Ikea to be exact) No apparent curse at all! Ride it, it's fabulous!
