I’m terrified of everything and violence is the default. I blame my mom for watching so many horror movies when I was a kid. One time I was work and saw a shadow scurry by my foot, panicked, and immediately stepped on it. Was a mouse.
Okay but adults can choose to undo a bad habit. It doesnt take that long, maybe a month. It helps to learn about the bugs and what they do, how they live.
If I were in your shoes I think the accidental mouse killing would have been a catalyst for that. Ive never killed an animal though and I’m already vegan, so theres no way to know for sure.
No Way takes a month. Took me 6 months to set the towels the way my partner wants it. And the socks? I still miss it up if I’m not paying attention.
So fun fact, The first childhood house was infested. Apparently I suffer massive trauma from a large number of bugs falling on me from weak ceiling that I mentally blocked out. Mom thinks its why I destroy them on sight with Astartes zeal. Frankly, is this way better than when I was a child. I remember crying at the sight of a bug until about elementary. Couldn’t even see a animated 2d bug without minor panic attacks. Then fear turned to a purification crusade*. *(while Im inside, outside is all them unless mosquito, wasps, ticks…etc)
