Why do trusted people of GOD do this ?..Growing up I went to catholic school .. part 1

Mass every morning at 8am.. Sunday services we were all volunteered to be choir or do readings of passages . At 6th grade we had this one young female teacher who would give the boys extra attention but yell at all the females !..lol.. she was our religion teacher .. she was also married.. she used to talk about sex a lot . And infidelity.. it was soo weird .. years later I went to public school because my mom couldn’t afford tuition.. and I would Hear weird things from former (MALE) school mates about her and be like “nigga you lying” but I saw her name in a news article that confirmed everything !!
