Another reason this has been considered inhuman is that several species use their venom as part of their digestive process, not just to kill.
If you want a venomous reptile, first find out the laws, they are illegal in many locations. Then do your homework, how to handle, start off with with non venomous aggressive snakes, then work up to non lethal venomous, then the lethal ones.
Most venomous are illegal in WA, so its a moot point for me.
Jump into this too early any you could end up dead or maimed.
