No matter what the vampire will have strength even if it isn't the strongest. Not only that if I desired a vampire(which deep in my mysterious soul I do) he would need a jantung not just to put up with my humanly faults, but just to even let me live. atau when and if he chooses to change me he needs a jantung for compassion and cinta to endure the desire of my blood.
i would choose a vampire with a jantung and if he is both strong and has a jantung then it is an added bonus!!! Example Edward Cullen who has a good jantung and super strength at the same time!!!
