Kill a tree,I thinknot.

Spikes will not kill a healthy tree by themselves. It is much more likely that atree which has diedwas weakened by drought or defoiliation from insects or disease,than someones spikes. I have been a Arborist for the last 27yrs andhave used spikes/nails and lags for years puttinguppermanent stands, many of those trees are still standing, alive.

Iuse climbing spikes(gaffs) as well and while they willdamage the bark theywill not kill a healthy tree. There are newer andbetter ways to get up to my stands but it is hard to teach and old dog you know.
