It depends on what country you are going to be fighting for and if they are in any conflict at the moment. Not everybody wants to fight for their country. regardless of what they might owe their country as a loyal citizen.
I have to do military service at the end of my education and I come from Afghanistan. There is a real chance that I can be killed while serving for the sake of my country. To my government, I'm just some faceless nobody that's another body thrown at their army. So if it's that kind of situation, I can understand.
But other than that yeah OP you should go for it. If your still against it though, some commitment like school/only source of income for family or faking a medical issue will get you out. Also if you reside in another country and have dual citizenship, you can just revoke your citizenship and you won't have to enlist.
