Fallible (imperfect), YES, we ALL are.

Some altruisms:

A woman can have many flaws.
A man can have many flaws.
A woman can have only a few flaws.
A man can have only a few flaws.

Types of flaws:
1) character flaws.
2) Philosophical flaws-thinking incomplete thoughts according to a self-serving bias (a selfishness that is bad) that unjustly imposes on other people's human rights of happiness. Laziness can also cause a False Logic to be "preferred", bad judgement because of time constraints, subconscious self-persecution from conscience can lead to a bad attitude towards others.
The list could go on and on, but to what avail?

Who determines (defines) what a flaw is?
In humanity, flaws are not absolutes (there is no OBJECTIVE determination of what is or isn't a flaw). They are all SUBJECTIVELY determined/chosen (with a bias). So, who is to say that humility is a flaw?...only the person who has not yet learned to value it and see the beauty of it.

The biggest flaw there is in the whole world is that we determine others to have any at all (judgemental). Being judgemental will prevent you from truly enjoying life and being happy. Their business, their thoughts, decisions, opinions, attitudes and feelings are their own and should be respected as their own and should not be subjected to either your approval or disaproval. A control freak NEEDS to be judgemental of others in order to distract their own conscience from their own flaws and recieves poetic justice by not being able to think of themselves as a fair and just person. Their conscience will nedd defense for the rest of their lives and prevent TRUE happiness (POETIC JUSTICE and vicarious condemnation will never end).

So, do yourself a favor, do not determine anyone to have flaws.
