They're both killing for the sake of 'religion'.
What? Seriously, what? I am so confused and repulsed by that statement, please elaborate.
And *again* most persons consume or dispose of the sacrifice appropriately as was often (but, again, not always) done in antiquity. Meat was an incredibly expensive product and often a luxury. The only time a normal person could have some guarantee of meat was when excess livestock were killed in the fall to cull the herd and provide food for winter and extend the available fodder for the remaining animals. Thus, generally leaving a sacrifice to rot was a waste. There are as always exceptions to this but no modern legitimate practitioners that I am aware of leave rotting carcasses as a form of worship.
