Do you think it would not have been worse if he had a gun?
It would have been worse if he had a box of dynamite, or a truck load of cobras, or ....
You always miss the point. Hence the ample number of
Swooshes in your collection.
Let me explain it for you -- I'm sure not for the first time.
Gun control promises safety from violence, especially murder. But, gun laws don't stop killings (e.g. these mass knife murders). What gun laws do is take away the ability (and right) from everyone to defend themselves against a lunatic going on a stabbing spree.
So, is it better because the attacker didn't have a gun, or is it worse because nobody else was allowed to have a gun? How many lives could have been saved if only one law abiding person had a gun on them and stopped the attacker long before the police were called?
You accuse us of seeing everything as black & white, yet you can't turn your focus anywhere other than the attacker. Try focusing on the intended victims and how they might have lived if they had only been carrying a firearm.
