Guess the movie

The main character is single-minded in his mission of acquiring a weapon
He believes that this weapon will give him the power to vanquish his enemies and there is an elaborate fantasy scene where these enemies retreat in abject defeat due to the overwhelming power of this weapon
He engages in both overt and covert propaganda to obtain the weapon (e.g. subconscious propaganda and documents stating his intent)
However, he is rebuffed by an agent of the government, a quasi-religious figure, and the main authority figures in his world.
He uses vile language and tells untruths.
He engages in other challenges to authority and subterfuges involving, for example, code-breaking and an obscene disguise.
All the while, he is threatened with force by a dominant figure (described as a bully)
This dominant figure is accompanied by another (described in amphibian terms) who acts tough but, without protection, promptly retreats when faced with danger.

Later, the main character stands up to that dominant figure and his weak ally.
Although he commits an unpardonable sin in the process, a member of that main authority fails to report it to the other member of the group and the danger passes.
A disagreement forms between the members of this main authority group on weapon policy.
He acquires the weapon.
He promptly misuses the weapon and causes the very damage warned about from the start.
