Without seeing the extent of the damage, it's impossible to say if the damage might cause a short/start a fire, or pose a shock hazard, or both; you could be seriously injured or killed. There are suggestions to tape the wire with electrical tape. This can be done, but be extremely careful.
Due to the wires having electrical resistance, which means that they resist the motion of electrons, the electrons bump into atoms on the outside of the wire, and some of their kinetic energy is given to the atoms as thermal energy. This thermal energy causes the wire to heat up. Electrical burns occur when you hold on to a wire, and due to heat transfer, some of this thermal energy is transferred to you. When the wires get hot enough due to a constant input of heat, there will be more heat to transfer to you if you touch the wire, and all of this excess heat can cause burns and fires.
