What about if that country especially helps other countries to fight for there freedom and protects them from imperialist view countries and with that saves lives in that countries?

Who's that?

My country Georgia received a help from the USA and EU countries when Russia invaded us. Their help saved lots of Georgian people lives. Another example Ukraine, USA and EU countries are helping Ukraine to defend themselves against Russia. Only people that never saw real war think that improving the defense of their country is "killing people" when in reality it is opposite.

Realities get murky when you talk geo-politics. Some times it's in the interest of the US, to protect the self-determination of a nation, especially when it goes against the interests of a geo-political adversary. We see this with your country, Ukraine, Latvia, Lithuania, Estonia, etc.

At other times, it means selling F-16s, Apaches and munitions to Saudi Arabia, so they can carry out a brutal bombing campaign in Yemen. There are no good or evil regional powers, only national interests and the smaller nations which either get in the way of those, or help you achieve them.

Be that as it may, it still matters how the people in power think and behave. Some systems of government are better suited to reduce violence than others. For example, a dictator is probably more likely to order military intervention than a person who has to justify their actions to advisors, a congress and eventually a whole nation.

Obviously as you say things get murky when there are large interests at stake and no side is wholly good or wholly evil, but still some can be more wrong than others.
