Republican Christians in this sub: Is there anything Trump could do which would make you stop supporting him?

I voted for Trump in 2016. I was a Baptist pastor. But my faith and politics evolved and I came to a much different place. I also came to see Trump for the horrible selfish flawed individual he is and I honestly think my support of him in the past is one of my greatest mistakes. I am curious if he could do or say anything at this point which would cause Christians to stop supporting him.

I know everyone's sick of the political posts but the man will be the next US pres and we are all processing this.
