The best way to make a group of brute men listen to your orders and never attempt to betray you is to show them that you are strong enough to kill them.
To make others not think of betraying you, the best way was to install fear in them, as fear is a powerful motivator.
Establishing yourself as a formidable force will ensure their loyalty.
By demonstrating your strength and ability to overpower them, you established yourself as a force to be reckoned with.
Only then would they understand the consequences of not obeying your orders and be more inclined to listen and follow through.
By instilling fear in others, you create a sense of dominance and control, making it clear that crossing them would have dire consequences.
As well as removing the bugs that infest his group, it will serve as a constant reminder of his power and ability to decide their lives.
