I remember my padi instructor (British, in Malaysia) as being completely paranoid, which was a good thing. He essentially told us that any missteps would have very nasty consequences, and spent most of his time badgering us with safety precautions. He also encouraged us to dive with a guide, do refresher dives, etc. The only downside is that I don't dive anymore now that I have kids, since I believe it's dangerous, and I'm worried I will make a mistake...
