Call me naive, but I don't believe that big companies assasin enemies.
Killing someone means that the people on top of that company take the risk of a revenge or punishment. For all their life afterwards. I don't believe any millioneer wants this - all he wants is to spend his millions in peace. Those of them that don't mind living in fear respectively live the much more interesting (challenging but rewarding) life of a criminal boss.
You're quite naive ..lol ..you asked for it, mate
just joking, bro..
Have a good one.
