The above was something which I lived by for the past 8+ years, ever since I became a vegetarian.
I am proud to say that I have not intentionally kill any insect, animals etc. since that time.
However, when I came to my new office, I had to succumb to killing ONE type of insect - roaches! Oh my God, they are everywhere! Thank goodness they are not the mega huge ones which fly too, just tiny little ones.
But the horrifying part is that they crawl out from your keyboard and they leave their empty eggs there too! So it was very disturbing for me in my first few days. I tried to just dust them away, but they kept coming back.
The secretary said that "You must kill them, else they will breed further!" So I had to lor, else they will be all over my desk!
May God forgive me for this sin ....
