Actually blood doesn't make it more serious. I'll take as example Tarantino: rivers of blood doesn't make it more violent, it actually gives it a cartoonish feeling. Bad treated blood is worst than no blood. In the case of Hisoka I think it makes sense, since the cards are sharper and got in the skin they caused internal damage (If not there is no way those cards would have killed it anyway) rather than external bleeding.
:/
True. Realistic blood/bleeding is actually a bit difficult to draw since many manga artists probably have not actually experienced anything
like the hyper violent worlds that there characters are a part of. I mean I write comics and many have rather violent themes but thankfully
I have not actually experienced seeing such violence. I mean I've never seen someone get shot and I'm rather glad about that actually.
I think most artists or writers would be like me where they can only imagine how graphic something like that would be. Of course you
don't actually have to see someone get shot in real life. You can always watch videos of people getting shot in real life (I'm sure there
are plenty.) But while I may or may not have the stomach for it ( honestly I probably don't) I would feel rather guilty watching another
person get shot. Whether or not I should is another manner but that's just how I would feel. I can stand fake violence much more
because I know it's fake. For the most part blood isn't gross to me but at the same I have my limits and I prefer not to be tested.
Some people get their kicks out of watching torture scenes but I don't. Yes I do think torture can make a story interesting but I
don't believe the reader has to "experience" the torture to understand the character has been tortured. I'll take your word for it.
Though I'm only speaking for myself as far as my lack of experience with violence. While I wouldn't expect anyone here to have
witness much violence I wouldn't rule out the possibility. Of course even if you have experienced much violence. That doesn't
mean it's going to be easy to draw because well drawing isn't easy.
