It did not make me feel invincible, superhuman, violent or angry.
...I did feel a bit more like "the Hand of God" when I was trained on the M60E3...until I saw an M2, and later an M242 Bushmaster.
Extended firing of any of those is one of the best experiences life has to offer. First hand experience aside, objective evidence is the VERY high price that a great many people pay for transferable examples and the wildly successful machinegun tourism (rental) ranges and events. People aren't spending that kind of money because shooting them is unpleasant or upsetting. On the contrary, it is quite fun and relaxing.
