Good thread this one. I'm a newbie too and the last thing I want to do is offend anyone, so I'll apologise ahead of time for any offence caused to anyone by my reply
. The OP asked if there was cruelty in bushcraft. I think it's difficult (nigh on impossible) to trap/ snare an animal without causing it some degree of distress. This can be seen as cruelty by many, yet to the person who is trapping to survive it is seen as unavoidable. Unpleasant, but unavoidable. If the animal is despatched immediately then any stress or suffering is minimised. However, it can conceivably be several hours before you check your snare. Nobody sets a trap and then sits by it all day waiting for it go off. We leave them because if we stayed too close there's a good chance the prey would sense our presence and flee. So we go off and do other things and come back later to check if we've been successful or not. How long has fluffy been dangling there, kicking and struggling? 5mins? An hour? Most of the day? How long is too long? This is something we all have wrestle with our own consciences about, and try not to make judgements upon others who do things differently for whatever reason.
To me though whatever side you take, the ability to make an effective snare is a nescesary skill for bushcraft, even if it's just a case of making one and then taking it straight down once you've tested it. Your life may depend upon your ability to catch another creature and eat it. Not likely if you're off for an overnighter in the local woods, but on Dartmoor or in the Highlands for example it's easy to get lost, and the rations you brought with you won't sustain you forever.
The best advice I can give is to practice making a variety of different snares and learn where best to place them. Once you're sure it will work, take it down. Then build another. Practice practice practice. But don't rely on trapping alone to provide food, foraging is an equally vital skill for survival in the wild, and often foraged foodstuff might be all that is on offer.
