Not Sure What to Do

The blemish notwithstanding, the Sages thought
to sacrifice the animal as an offering due to
the imperative to maintain peace with the government.

Rabbi Zecharia	If the priests do that, people will say that blemished animals may be sacrificed as offerings on the altar.
Sages	If we do not sacrifice it, then we must prevent bar Kamtza from reporting this to the emperor.
