I don't know how to feel about this. I feel bad because they died but then again they were both illegally basejumping
For next time, the default when someone dies is sadness--FYI. It's something in humanity that makes it so.
Furthermore, the US has made laws putting the Japanese in internment camps, mandating race segregation, regulating the trade of slaves, etc etc. U.S Law is not a great moral compass for how you should feel about a given activity.
