Not really - you can vote for candidates you pick yourself. You just have to convince them to run first and then convince enough of your fellow citizens to do the same and your candidate wins. You can run yourself too.
Do you need money and power to convince somebody? At which point you get what you want at a gun point, and why do you think it's better?
Frankly, when people have the option to vote and elect those who govern them in a peaceful manner, yet keep being unhappy with those they elect, how would killing each other will change anything? Sure the side that wins gets to pick the rulers, but are they going to make better choices, or agree among themselves when they had just killed a whole lot of people they disagree with?
At the end of the day you can't fix your own failures by killing other people.
