Sorry to be blunt, but anyone who has ever penetrated an active thunderstorm (for whatever reason) will do whatever it takes to never do it again.
Amen to that.
The most frightened I have ever been in an aeroplane is in the middle of a thunderstorm, going down. Because I thought I could get over the top of it. I did not get over the top, and because of the turbulence and buffet boundaries had to descend into it.
Only once. Never again.
The satellite weather trace makes the hairs on the back of my neck crawl.
