Frankly, I am surprised that Abbasi wasn't killed while in Vienna more so than the assassination of another Iranian Nuclear scientist. The scientists are logical targets in this case along with nuclear engineers working in or for Iran. If I were one of these scientists, I would be sure to treat my creditors, wife and relatives extra well because any of them could easily commit murder and blame it on Israel even if the real cause is a domestic dispute.
