Until we become intelligent enough to get our resources without hurting any other species on the planet, we'll keep defending our "own right" to life against anything else, and just try to minimize the casualties on the other "side".

Until we manage that, as the supreme species on the planet, we will get to arbitrarily decide what gets to live and what doesn't. All the other life forms are at our mercy. At least most of them aren't even aware of it.

well it is hard to tell without predicting the long term future. I mean if we eradicate all malaria something else may also happen as a consecuence that we were not aware now but is bad for us.

That's a rather different standard of right and wrong than you seem to support in your previous post.
