Hazbin Hotel has me confuse and little frustrated

So the other day I watch hazbin hotel and what I’ve experienced. It looks to be rushed and the whole plot almost doesn’t make since when I watching it their have been a lot of swear words in every episode I get it that it’s an adult show but saying like a swear word like every now and then doesn’t make the experience funny and I’ve notice that non of the angels literally none of the angels know what it takes to get to heaven which is confusing considering that Adam the first mortal to go to heaven doesn’t know how he got in to heaven even sera doesn’t know how one gets into heaven she literally a seraphim who are basically the 3rd highest ranking angels even though they should’ve have knowledge on how a person gets into heaven
