It depends, we as Muslims Can’t say so and so is going to hell without a verse or a sahih hadith. The only people we know who are going to hellfire is Abu lahab and his wife, Pharaoh and others.
If you disbelieve in Islam knowing it’s the truth after Allah showed you proofs and signs and you disbelieve then on the day of judgement, you’ll be judged justly and end up in Hellfire. If you didn’t receive the message of Islam while you were alive or you were confused about Islam then on the day of judgement, you’ll be tested there fairly (you will have your own test) and Allah knows best.
Because worshiping the one who made you and gave you everything is the most grateful thing you can do, neglecting it would be a horrible thing to do. Your breathing, walking and seeing because of him.
Instead of just thinking about the negative, think about the positive. Allah doesn’t want to punish us and that’s not his intention! He’s the most merciful. Even if your sins reach the skies, Allah would still forgive you if your sincere. Allah tells you do not despair or lose hope in my mercy. If you sincerely believe and worship him, he will grant you paradise and eternal happiness.

Your other question about The evil actions done on the victims and why God doesn’t intervene. This world is temporary, all types of injustices will be held to account on the day of judgement.
Also you need to keep in mind this world is a test and God tests every individual Human being in different circumstances. He does it to bring out the best of faith from people. Even the prophets suffered like Prophet Ayub (as) suffered with an illness because he was being tested by Allah. Allah gives certain people power and wealth to test them and Allah tests certain people with hardships to bring the best out of them.
Allah says in the Quran - “
And We will surely test you with something of fear and hunger and a loss of wealth and lives and fruits, but give good tidings to the patient“ (surah 2:155)
Was that clear?
@YourBroMoe I hope you understand and May Allah guide you.
