Unresolved issues and roots - Proverb 30:21-23

Proverb 30:21-23
This speaks to me of unresolved issues in life. "a slave when he becomes king" this reminds me of Chairman Mao in China, he carried all the resentment and hatred in him, and when he became the chairman, he ruled the country with hatred and torture. "unloved woman when she gets a husband" when carried with jealousy, bitterness, rejection,etc, the wife will not be a blessing to her husband, but will treat her husband from her roots of insecurity, jealousy,rejections, hatred..etc and will make her husband's life miserable.
The roots in us, when unresolved, when they get a chance to manifest will bring disaster to the people around us.
