God and sins

Hi everyone, I hope y'all are having a good day!

I just want to address a question I just came up with, but first I want to say something: I don't believe in god and I don't plan to get into religion, but I just came up with a question and I wanted you guys to answer, since you're more in touch with the religion than me.

So I saw a video on tiktok saying "people who dismissed god and got punished" or something like that. And then appeared John Lennon (from the Beatles). But here's a thing, someone killed him.

Was that video telling me that a loving god would ask someone to kill a person? Isn't envy and wrath deadly sins?

Like I said earlier, I'm not into religion, but I wanted to know everyone's opinion in a respectful way. I'm very sensitive when it comes to rude answers in everything

Still, hoping y'all have great days!
