The ritual of the passover lamb in Torah takes the life of innocent, precious and feeling beings

Hello!
Do you think that a God full of love and compassion would sacrifice hundreds of thousands of innocent lambs?
They haven't done a single evil.
Is it just to endorse the killing of innocent, sentient and feeling beings?

Lambs want to live, they love their family, they have the right to live. They feel suffering, and the suffering for the mother of the lamb, when someone is killing her child, is immense.
