How did giles corey die? why did he refuse the "answer the charge"?

If Giles pleads guilty, he will be granted spiritual reconcilliation; and be hanged.

If he pleads innocent, he will be found guilty and will be hanged while his soul is condemned to an eternity in hell.

Both scenarios would result in the crown stripping him of his land and assets leaving his sons and wife starving and penniless.

By remaining silent, the courts can neither confirm or deny his innocence; and as a result cannot take away his property.

By enduring torture in silence, Giles ensured his families longevity by sacrificing his life.
