Do you agree or disagree with the following statement?

[Always tell (should be "telling") the truth is the most important consideration in any relationship between people.]

I don’t agree the statement that always telling the truth is the most important consideration in any relationship between people.
But I would agree with the statement if the sentence changed as to, “Always telling the truth is the most important consideration in any relationship between people, except some special situations.” I really believe we should tell the truth and be frank except in some situations. The truth sometimes will hurt the person‘s heart in some situations, so lying some white lies is never mind (never hurts? okay? alright?).
For example, a girl today changes her hair style and she asks you how about her new hair style. In fact, you feel that the style is weird, but should you say “Oh my god! What happened to your hair? It’s so weird.” If you really say the truth out, the girl will be so sad and that hair style could be a nightmare in her life. Then, maybe she can’t change her hair anymore. So why don’t we just lie tell some white lie such as ”Your hair style is not bad. It’s special.” Saying some a white lie can make her mood happy and will not hurt her heart. Therefore, why don’t we do that?
But I still agree that we should honest to treat anyone at in most situations. Because if we say tell a lie, we would need to say tell more lies to achieve establish the first lie, and while saying the telling lies is can easily to become a habit. I suggest everybody should tell the truth. Never hurt others in order to for self-benefit, or you how you to treat others, and will be how others will treat you by the same way, too.

Do you agree or disagree with the following statement?

[Always tell[ing] the truth is the most important consideration in any relationship between people.]

I don’t agree [with]the statement that always telling the truth is the most important consideration in any relationship between people.
But I would agree with the statement if the sentence [was] changed [to] “Always tell[ing] the truth is the most important consideration in any relationship between people except [in]some special situations.” I really believe we should tell the truth and be frank except [for]some situations. The truth sometimes will hurt the person‘s [feeling] in some situations, so [telling] some white lies [is permitted sometimes].

For example, a girl [has just changed] her hair style and she asks you [if you like] her new hair style. In fact, you feel that style is weird but [would] you say “Oh my god! What happened to your hair? It’s so weird.”

If you really [tell] the truth [], the girl will be so sad and that hair style could be nightmare in her life. (This is a difficult sentence. It is not how an English speaker would write it. However I may unsure of an alternative construction). It is this part that I have difficulty with "that hair style could be nightmare in her life"

Then, maybe she [won't] change her hair anymore. So why don’t we just [tell] some white lie such as” Your hair style is not bad. It’s special.”

Saying [a] white lie can make her mood happy and will not hurt her [feelings]. Therefore, why don’t we do that?

But I still agree that we should [treat people] honest[ly] [in] most situations. Because if we say a lie, we would need to say more lies [as a consequence of] the first lie and saying [] lies [] eas[il]y [becomes[ a habit. [So] I suggest everybody should tell the truth. Never hurt others in order to self-benefit [or] others will treat you [] the same way[].
