I'm not justifying anything. I'm saying that awareness alone does not make humans worse. If other animals do the exact same things as humans then why are humans worse? It seems that the distinguishing factor, is that humans want to imagine that they are special, so they get an automatic "worst ever" categorization on anything they do, simply because they are humans. Not because they do anything actually different.

The only thing you called out about humans being different is that they are capable of noting that other animals behave the same violent ways. So you are basically saying humans are worse because they are observant.
