Uh, I suggest you read your Bible a little more thoroughly, maybe starting with the following:
Yes, "God is love" - He does love everyone and wants all to be saved through His Son, but He hates sin because, in His holiness, He cannot tolerate sin. He will reward those who turn their lives over to His Son with eternal life with Him, but He will send those who do not turn their lives over to His Son into eternal punishment.
“Genesis 12:3, Proverbs 3:33, Malachi 2:2, Genesis 19:24-25”
Yes, I know. Now find me one in the New Testament; and not just a reference to “a curse”, “he was cursed”, or similar, but “G-d cursed.....”.
