It's a little piece of lead and is lethal right? Well, it's only lethal if it gets inside you. If there is enough voltage to push a lethal level of current into you, and enough of that current is actually available to push then it is lethal. For it to get into you, it needs enough voltage behind it to push into you.
200mA is lethal (actually much much less is lethal) and can kill, but only it if gets inside you.
