Hi Antaiwan,
Well if you feel disgust - loathing - hostility towards a person to a degree that you do not even want to be around the person, that would be a good indication to me. This is the way of the world, to find fault with others and hate them because of it, we can see it all the time.
I have to throw this is. God has called us out of this world, not to do as the world does, but to be different, to not judge others at this time.
1Jn 2:15 Do not love the world or the things in the world. If anyone loves the world, the love of the Father is not in him.
It is He that has put us all on our path, even the world. Only by the indwelling of the Holy Spirit, of course, can we love those in the world.
Mat 5:44 But I say to you, love your enemies, bless those who curse you, do good to those who hate you, and pray for those who spitefully use you and persecute you,
v. 5 that you may be sons of your Father in heaven; for He makes His sun rise on the evil and on the good, and sends rain on the just and on the unjust.
mercy, peace and love
