depends on multiple conditions
well besides the iron can be entirely discounted because its bonded and thus not conductive
and in its raw form besides being somewhat more sticky than water mixed with rocksalt its a worse conductor as it also mainly relies on the water and salt content for conducting electric charges
and after being exposed to air and electricity it should coagulate which should also decrease the conductivity after a short time
ofc isekai blood may work differently but thats atleast the case for our rl-version of blood
edit: all in all if that maniac has open wounds which get also splashed it should do the trick of bypassing the resistance of the skin without touching the wound directly so it should still work somewhat in the short run
metal spikes on a full metal shield or metal wiring should have done a better job imo (maybe later on)
edit2: direct contact of the charge and the conductor would still be necessary as air is a very poor conductor
