The three quotations that support the central idea that Brutus thinks Caesar is dangerous and needs to be killed before he becomes even more dangerous are:
- “Fashion it thus: that what he is, augmented, / Would run to these and these extremities;”
- “Th’ abuse of greatness is when it disjoins / Remorse from power.”
- “And therefore think him as a serpent’s egg / Which, hatched, would as his kind grow mischievous, / And kill him in the shell.”
These quotations express Brutus's belief that if Caesar continues to gain power, he may become a threat, and he uses the metaphor of a serpent's egg to illustrate the need to eliminate the danger before it fully develops.
