Was the Evil One who murdered 149 passengers and crew on the German airliner a PG or HG pilot?
I have just learned this mass murderer crashed the airliner into one of his favorite free-flying areas.
Germany is in shock. Hopefully, this information is incorrect.

If that's true, is it possible that hitting someone on the ground or in the air at the flying site was part of the motive?

Just an "area" popular for flying, not a "site."
