It doesn't take much to speak bad about a person and highlight their shortcomings and faults. Done it myself, we all have done it, it's human. It however takes character to speak well and fondly about others.
"Do not speak evil of one another, brethren.
He who speaks evil of a brother and judges his brother, speaks evil of
the law and judges the law" (James 4:11 NKJV).
