Should we care about others and come out?

It has to be a personal decision. I don't think this is something you can ask on the internet, as all our personal experiences vary widely. You'll just have to sit down and take some time to evaluate your circumstances, and figure out what are the possible outcomes of coming out, and would it be worth it. For most gay men, we have to wait until we achieved a certain level of success, and or professional siniority before we can come out. Bottom line, You have to decide.

But outside from that, coming out should be a matter of YOU. Do you feel trapped with the way things are? Do you wish others can know you better?

Most of the people who genuinely love you will not give it a second thought, as they know YOU didn't change. Some no matter how close they are you may never tell. you have to learn how to accept that too, especially since you are making that judgement. Keep in mind that there will always be a certain level of "don't ask don't tell" involved in your life depending on what your chosen profession is, mainly because you can't always control the ones you are surrounded by in such settings. You CAN however construct your best and most rewarding personal life, you CAN choose your friends.

I suggest if you have a particularly close open minded friend, you start with them. It can really help to have at least one supportive person with no axe to grind to help you sort things out. For me it was my adoptive older sister. Good luck with your decisions, I wish you the best.

Or even worse, jail or death in less civilized countries.

So don't just come out. Use your head and weight the costs against the benefits.
