How do you justify eternal hell punishment for shirk? [not a duplicate query please read full]

Every punishment has its severity according to its crime. So even if someone does delibritly shirk and by doing that obviously nothing would happen (affect) to the authority and Allah's power or oneness, so why so much hatred and severe ( eternal punishment ) that it doesn't have any actual consequence to Allah's power and dominian. Even if you somehow justify this, still it won't make sense, because if shirk is a sinn to be that great "unforgivable and intolerable" then Allah woudn't create this world or atleast those people who would do shirk ( based on his knowledge of the future ) . So its a catch 22 situation, if sin of shirk is that much "hated and intolereted" then God wouldn't Allow this creation on the first place because of the "hatered and intolerable" the sin of shirk is, if he Allows the creation (with it's sins of shirk) to happen then it means it shouldn't be an unforgiven sin and obviously no eternal hell as punishment. Imagine it for yourself, if you hate something unconditionally will you allow that thing to happen (if you have the power), if yes,then in reality you didn't hate it to begin with.
