Eric Bent actually didn't have many options for dealing with Joe Ga.
Joe Ga's display of "not being greedy enough" and "caution" left Eric Bent very helpless.
Were Joe Ga and his P·B really that important?
From the perspective of capability and scale, not at all!
But Joe Ga held the drug channel that could compel the Glorious Society to compromise, and he himself was an important target of the Glorious Society.
Betraying Joe Ga in negotiations with the Glorious Society was certainly impossible, as any rational person would know that it would only fuel the Glorious Society's greed.
But if it came to the last resort, in a situation with no other options, Eric Bent would use an "irrefutable price" to make Joe Ga compromise and facilitate negotiations between both parties.
This was certainly a last resort, but under the current circumstances, Eric Bent and the bigwigs behind him really didn't have many options.
