Safety? I'm quite sure Singapore is a much safer country than Germany. The US, not so much...
But if you've already moved to Singapore and you want to live in a safe country when you're older, it would make no sense to leave Singapore, unless maybe you're moving to Japan. Western Europe is of course generally safer than America (very little gun violence, after all), but Singapore is one of the safest places on the planet. Just don't walk on the grass.
