You’re spouting an oxymoron with those two statements.
If evil is subjective, then how can laws be made against it? How can you ever denounce a place that or person that says murder is good?
I don’t think you realize what moral relativism actually is, you just sporadically use it when seemingly convenient in a discussion .. but you don’t own up to the consequences of it. Thus, your claims are hollow.
If you want to be educated on Catholic theology, I’m happy to oblige.
The church wasn’t always good, which Catholics understand as it’s led by man, thus able to be led astray, but never abandoned by God and will always be corrected, as it has throughout history. There were anti-popes and occasional dark periods in the church. But murder was never not evil, the morality and theology never changed.
So no, what was “evil” never changed. Man simply corrupted the institution for certain time periods
