In my understanding in buying options you can only lose the premium you pay upfront. Selling options however you can get burnt.

Depends. You can sell a in money call, and buy 2x out of money calls. You only lose if the asset's price falls between your sell/buy.

The point is selling isn't bad. Its not managing risk that kills you. And for this poor dude it did.
