“For if God did not spare the angels who sinned, but cast them down to hell and delivered them into chains of darkness, to be reserved for judgment.”
and delivered them
“Delivered” means to give over to something else. God handed these fallen angels over to another place with a view to judgment. God will give them their due. God is consistent with His character. Either God must judge Jesus for our sins our He must judge us for not accepting His payment for our sin.
God sent Jesus to the cross to resolve our acceptance to Him.
There is no judgment for the person who receives Jesus as his Savior (Ro 8:1) because Christ died for his sins (1 Co 15:3). Jesus paid in full for any sin we have committed or might commit (1 Pe 2:24). Jesus took our curse (Ga 3:13). Immediately, at the point one receives Christ’s death in payment for one’s personal sins, a person passes out from under judgment and enters eternal life.
Jn 5:24, “Most assuredly, I say to you, he who hears My word and believes in Him who sent Me has everlasting life, and shall not come into judgment, but has passed from death into life.”
