This is the time to wait for a good accident investigation. Lots of things can go wrong; what brought it down remains to be seen.

T-storms can be really vicious - pilots usually go to great lengths to stay out of them. It will be interesting to learn how severe these were and why they weren't or couldn't be avoided.

Lightning striking composite surfaces can be more of a problem than lightning striking metal surfaces. Composites need associated conductive surfaces to route lightning energy away.

Electrical failure is a matter of degree. I don't know how the A-330 controls cabin pressure, but losing electricals and cabin pressure together might suggest a combination of problems. There is also the question of whether the lightning strike affected the fly-by-wire systems.

Severe accidents usually have more than one cause, and this one might take a while to get answers.
