Is my own heart in the right place?

Chatting with the Texas man gave me the perspective upon self reflection. On this forum we often say modernity is depraved and in a moral decline, which isn’t wrong, but what about introspection upon ourselves?

Are we depraved ourselves? What of our own heart? Or own actions? Humanity is prone to sin and do wrongs, which is why Jesus (from the Christian perspective of course) is needed(works through faith)

What are your thoughts? Yes, the OT view i held is coming in conflict with the Christian view I once had.

Yes, without a self-examination, no change is possible, because it's only after we realize what's wrong with ourselves that allows us to reevaluate our thinking and behavioral patterns, which opens up new perspectives.

People sometimes gave me a negative feedback, pointing out my "sad", "angry" or "arrogant" look - I had no idea what they were talking about. It took me many years to realize they were right, because my face and facial expressions only reflected what was going on in my mind, yet I had thought no one would notice unless I decide to permit them see. Thinking retrospectively, many of my conflicts with other people that often escalated to verbal aggression were of a malevolent origin stemming from my disordered thoughts, not necessarily related to the subject of conflict but still leaving a "fingerprint" on my face. People even apologized to me during conversation for no apparent reason. Lesson learned - the response from others often appropriately mirrors your emotions, not how you want to be seen by others, so any attempt to correct your behavior or self-presentation without addressing your background motives and emotions first cannot work adequately.

Bible warns against haughty look and mentions consequences of demeanor related to a wide array of "behavioral shortcomings". I can then easily imagine someone getting killed, losing a job or facing any form of conflict without even saying a word.
