Any way to get a quick kill is ethical
BINGO!!!!
And if you can do it shooting 1 month or 12 months a year what the heck is the Difference??
What is ethics then?
Its doing what YOU can sleep at night with. If you can truely look in the mirror and anylize you actions and feel good about the decisions you made - thats fine by me. The bid hitch to the whole thing is that "ethics" are like opinions - what is right for you may not be right for me. Neither is more right or more wrong in the grand scheme of things.........just different.
Your way is not the only or even the best way, stop thinking it is.........
