You worry and fantasize too much.
How many people have fallen victim to a predator attack in Europe in.... say the last 200 years?? Dogs and above all humans are far more dangerous.
If you're in the UK or large parts of the European continent, then you only need to worry about boars, so study them and learn their behaviour. That would take away a ton of unnecessary fear and worry.
Wolves in their normal behaviour will mostly try to avoid human contact, although we now have a issue here with wolves coming into populated areas. That probably will become a problem when it comes to livestock and dogs. Bears around here keep to themselves too, but if one is suspected to be in the area, make noise. They too, in their normal behaviour, will try to avoid you.
If they come into camp then you did something wrong and attracted him. Probably by leaving food lying around. Yes, eyeing a wolf or a bear in real life is a exhilarating experience and learning about having them in your backyard is too, but we should be rational and leave all those red riding hood stories behind us and learn about their ways. Their real ways.....
Moose on the other hand are the most dangerous animals around here. They are the most unpredictable ones. They might stand still and watch you, deciding to turn and run or they might charge, stomping you into the ground. Especially if there are calves around.... or maybe in brunst.
In any case; study their behaviour and stop worrying, but still be carefull. The only things really interested in eating you are mosquitos, midges and ticks.... and they only suck you dry. Bit like taxes and banks...... but often less harmfull.
Greetings from an area where moose, wolf, bear, lynx, fox, marten and other dangerous critters leave their mark regularly.....
