How we end up doing things wrongly without realising it.

Souce

Making of wrong decisions or doing things wrongly is one thing that no human is able to avoid, because it makes us human. The only problem is how we work towards correcting what we did wrong. But the problem nowadays is that not all mistakes are meant to happen, sometimes, it's as a result of our own doings.
There are a lot of things are often Leads us into doing things wrongly and they are;

_Anger
_Bad insight/ignorance
_Heartbreak/Sadness.
_Pride/Arrogance.
_Drunkenness

ANGER
This is when your mouth and body works faster than your mind. When you are angry, your emotions becomes heightened and You will begin to act and talk in the opposite and negative way, which is something the normal you wouldn't do.

BAD INSIGHT/IGNORANCE
being ignorant leads you into making a lot of mistakes because, you tend to do things wrongly when you have got a bad view of things, or lack of knowledge about things. When you see things the wrong way or when you are unaware of things, it leads you into making a lot of mistakes. The only remedy for this is knowledge. And Knowledge doesn't just come to you, but rather, you should be the one to make a move towards getting it.

SADNESS/HEARTBREAK
this is a state when you are feeling mentally uncomfortable because of a happening. You are sure to do things wrongly when you let your emotions get the better of you, because when you are sad or heartbroken, you say or do things you don't really mean just to console yourself.

PRIDE/ARROGANCE
Like the saying goes, "pride leads to a fall" This saying is inevitable to all proud people. So when you feel that you are better than everyone else and nobody can tell you what to do, then you are bound to make a lot of mistakes because nobody knows it all. And when you act all high and mighty, no one will want to correct you when you are heading towards making a mistake or give you a headlight when there is trouble coming, because they will want to see you fail/fall.

DRUNKENNESS
This a disturbance in behaviour or mental function during or after alcohol consumption.
You aren't yourself when you are drunk, so you are bound to make a lot of mistakes, which might sometimes come back to haunt you when you become sober.

The thing is, all this listed above could be avoidable but its all left to you whether you want to avoid them or not.

How you could avoid them.
_you could control yourself when you are angry by distracting yourself with others things like workout or meditation.
_learn to explore things, and always ask questions when you aren't familiar with things.
_don't stay on your own when you are emotionally down because it could lead you into doing things you might end up regretting or won't live to regret.
_Proud people are mostly lonely people because no one would want to put up with a proud person. Like a wise man once said proud people always end up running helter skelter
So there is literally no gain in being proud.
_Most people get drunk just to avoid their troubles for some minutes or hours, but that doesn't mean that the trouble will disappear when you become sober but rather, it will still be there waiting for you. So the time you spend trying to avoid those problems should rather be used to think of how to solve those problems. And
Besides, being drunk can sometimes add to your problems because you don't know what you did when you were drunk.
