Your brother has the doctrine of Hell as an idol of his heart, so he's going to use any passage of the bible where people died to show that God is the monster he really believes Him to be.
1Co 13:4 Love is patient and kind. Love knows neither envy nor jealousy. Love is not forward and self-assertive, nor boastful and conceited.
1Co 13:5 She does not behave unbecomingly, nor seek to aggrandize herself, nor blaze out in passionate anger, nor brood over wrongs.
1Co 13:6 She finds no pleasure in injustice done to others, but joyfully sides with the truth.
1Co 13:7 She knows how to be silent. She is full of trust, full of hope, full of patient endurance.
1Co 13:8 Love never fails. But if there are prophecies, they will be done away with; if there are languages, they will cease; if there is knowledge, it will be brought to an end.
1Co 13:9 For our knowledge is imperfect, and so is our prophesying;
1Co 13:10 but when the perfect state of things is come, all that is imperfect will be brought to an end.
1Co 13:11 When I was a child, I talked like a child, felt like a child, reasoned like a child: when I became a man, I put from me childish ways.
1Co 13:12 For the present we see things as if in a mirror, and are puzzled; but then we shall see them face to face. For the present the knowledge I gain is imperfect; but then I shall know fully, even as I am fully known.
1Co 13:13 And so there remain Faith, Hope, Love--these three; and of these the greatest is Love.
1Jn 4:8 He who is destitute of love has never had any knowledge of God; because God is love.
If your brother tries to refute that, it may be best to stop talking with him about the Truth because his heart is not yet ready (at this time).
I hope this helps.
In Him,
John
