There is no way Max would have been electrocuted in the bathtub. The computer went in there first and it would have tripped the circuit breaker (or blown the fuse.) By the time Max was pushed into the tub, the circuit would have been dead and there would have been no more electricity. Had Max been in the water when the computer went in, he could have been electrocuted (but the circuit breaker would have been tripped quickly and he might not have been killed.
