What do christions think causes hatred in the world?

Answer 1

Gal:5:19: Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness,

Gal:5:20: Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies,

Gal:5:21: Envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God.

The natural heart is bent toward these traits,and that is why God sent his son into the world to condemn sin in the flesh and to provide deliverance from it.

Rom:8:3: For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh:

Heb:4:15: For we have not an high priest which cannot be touched with the feeling of our infirmities; but was in all points tempted like as we are, yet without sin.

Rom:8:1: There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit.

Rom:8:13: For if ye live after the flesh, ye shall die: but if ye through the Spirit do mortify the deeds of the body, ye shall live.

Gal:5:22-25: But the fruit of the Spirit is love, joy, peace, long suffering, gentleness, goodness, faith,meekness, temperance: against such there is no law.And they that are Christ's have crucified the flesh with the affections and lusts.If we live in the Spirit, let us also walk in the Spirit.

The cause of hatred is sin.
