If all in one.....

[starnight1]

Lately by reading and meditation, i finally come to a place to connect and acknowledge that everyone everything is connected, we are al in One.
last year a teacher said the people we associate or strangers we meet in street maybe our fathers mothers sisters soulmates in past lives,i laughed, but now i agree.
same time it makes me in a wondering,what shall i do if war is happening?
shall I fight and kill the enemy?(the enemy maybe my past lives parents?) If i kill them i may save my country and people but i also cause a karma debt? If i don't fight then they will kill me and more.....
even if in daily normal life,if meet a thing such as disease. everyone deserves to be taken care of, but everyone will die someday too, everyone is also equal, shall i still care the body or let fate take?
shall i care my body firstly, or care the others'body, and why?

Mostly i will take action by instinct and by emtion, but these common things becomes a question now,
I hope to get some elightment,
sorry for these stupid confusion, and thanks for help.

The thing is in real life there is good and bad and you must agree that if you don't something good, you do something bad. As hurting others is very bad thing but it is as bad as they hurt you too which is why you prevent yourself from being hurt, as you mentioned about fighting, fighting is real and when it comes to kill, you either kill or be killed. So we always weigh what is greater than the other and hoping to do what is right.
