Hardin's metaphor describes a lifeboat bearing 50 people, with room for ten more. The lifeboat is in an ocean surrounded by a hundred swimmers. The "ethics" of the situation stem from the dilemma of whether (and under what circumstances) swimmers should be taken aboard the lifeboat.
Hardin compared the lifeboat metaphor to the Spaceship Earth model of resource distribution, which he criticizes by asserting that a spaceship would be directed by a single leader – a captain – which the Earth lacks. Hardin asserts that the spaceship model leads to the tragedy of the commons. In contrast, the lifeboat metaphor presents individual lifeboats as rich nations and the swimmers as poor nations.

Brutus relies heavily on his own conscience and will not agree to do anything unless he completely believes in the cause. This is why it takes so long for Cassius to convince him to kill Caesar. Eventually though, he believes that their cause is right and therefore goes into the murder with a clear conscience.
He also keeps the other men (especially Cassius) in check while planning the murder, because his conscience is so strong. He says "Let us be sacrificers, but not butchers, Caius." He is making sure they stay on track and are doing things for noble reasons, not just blindly killing.
