Pity the animals
One footnote of the War of the Currents was that Edison's side electrocuted dogs and other creatures to 'demonstrate' that Tesla's A/C power system was 'dangerous to the public', even though Edison's own D/C system could burn flesh and kill at high voltages. Kids were paid to bring stray dogs to be electrocuted. Demonstrations were made to show the A/C power system killing these unfortunate animals. One of the biggest animals electrocuted using A/C and the appalling event recorded on Edison camera equipment and credited to Thomas Edison was that of Topsy the elephant, who had killed a spectator, and was electrocuted to death some years after the end of the War of Currents, and footage of which can be found online.
Also, let's not forget the electric chair, which was in part created during the War of the Currents to make bad publicity for Tesla, indirectly, as Death Row prisoners would be electrocuted using the A/C system.
