"Product of Our Environment?"

Are we a product of our environment? I truly feel there is some weight to this theory. I used to feel we have control of what or who we become and ultimately our chosen decisions determine who we evolve to be, many years ago this statement would hold true to my beliefs. Many psychiatrists say yes and many more say no! Now, I still fully believe who we become and are is directly influenced from our gathered life experiences and decisions make or have made, either due to non-existent options and or our own ignorance or lack of insight, however, we do ultimately make those very decisions that determine who and what we identify ourselves with. Any psychiatrist who would disagree, truly never fully understood his or her chosen profession. No one individuals thought process and or circumstances in their lives can be equated to an exact science and fit into one of several different physiological categories! The decisions we make ultimately decide our final destination in who or what we become long term, however, even though our chosen path ultimately effects the final product, our acquaintances and or individuals we associate with have a great influence on this as well! Many who start out good in nature, when grouped with others who have less than desirable motives, and or when given no other choices and or are unable to see any other solution to their situation, many times we become a "Product of our environment". There isn't any true mathematical calculation to predict the outcome of any one individuals psychiatric make up. I don't care how pure an individual starts out, when given the same set of circumstances and limited resources time and time again, with no change possible within site, that individual over time will eventually become somewhat corrupt and or jaded. Much like a cancer gnawing at the healthy cells it eventually takes hold and starts to grow within their very soul. And without intervention or interjection of hope into their lives they eventually become consumed by their environment. I am in no way assuming that there is no turning back from here and that that individual can not heal and or recover from their unfortunate set of circumstances and or life choices. I do believe however that their very core has been fractionally effected long term, if not a lifetime. This is why evil grows like a tumor and spreads like a cancer! "Do unto others as you would have them do unto you" - "an eye for an eye" - Jesus Christ. It's that simple. And when someone calls them-self a Christian they are assuming a huge burden to reflect all that is good and the responsibility to convey God's love through their lives. I don't believe any one individual should ever attempt to convey what belief they are or even call them-self God's witness of sorts, without an immediate disclaimer afterwards "I am a man, I am not perfect, I was born in sin, of sin and Jesus Christ died for my sins, so that I may have everlasting life! Therefore, you will see me sin, you will witness hypocritical behavior from me and you should point out to me where I am wrong in my actions". Because, we all default back to judgement of others and that is VERY DANGEROUS! Especially when we ourselves can compare actions we choose to partake in, within our lives that are comparable to the individuals actions whom we falsely feel we have the authority to judge.
