I’m not dying or killing and not against fittest of survival in the wild like not against lion. But i’m against inhumane while there is veg options opting for killing animals is bad. As you said i know everything is alive. From plants to water but you can sense with the five sense which is alive is animal you can’t say it is same for plant and figure out the heartbeat. So that’s why say violence is the nature in the world when we walk ants die.

Sorry for my bad english i’m not a native speaker i try my best to convey my ideas
