Sometimes it is better to lie rather than make things worst. As they say, "what you don't know won't hurt you".
In my opinion lying is okay as long as it doesn't harm anyone. If you lie just to protect yourself or someone else and that lie doesn't harm anyone in ANY way, it will be okay. However, lying too much could lead harming yourself once people realize you have been lying all the time.
Being honest is easier in the long run. Or just don't say anything at all. Who wants to keep track of what you've said to who.
You cannot survive without saying lies. You'd have to be a hermit. Even then you'd be saying lies, because most of the time we're saying lies to ourselves. So the first thing is to admit that lying is an essential part of being human. If you can't even admit this much, you're an incorrigible liar. The second thing is that we don't lie only so as not to hurt the feelings of others. We often lie instinctively. A lot of times you'll say a lie, and a few moments later you'll wonder why you said it even though it wasn't necessary. Many lies are said because we automatically respond in a certain way in social situations. It wouldn't be advisable to begin weeding out all these little lies. It's enough to be aware of them, and not to continue lying to yourself that you never say lies.
A lie is lie in my own opinion and the fact of the matter is, everyone lies either for good or for bad. Honestly, It's best not to lie at all even if you would end up hurting people whom you care about because you've tell them the honest thing instead. It's brave to be able to do that, and somehow commendable.
White lies are petty lies. These are the things that does not require big decision. If you make it a habit of lying, then that's the bad side, I guess.
I don't believe in lying to myself or to others. There is such a thing as being honest and tactful at the same time. Why not speak your truth? Why not lay everything out on the table so people understand you and where you're coming from? How can you possibly trust someone who lies? It all sounds like big, messed-up unnecessary mind games to me. Why complicate relationships by playing those mind games? I'm determined to live with integrity and share my truth, even at the risk, that someone might dislike what I have to say.
Since everyone's guilty of lying at some point in their lives, I think that it really depends on the situation. If you're just trying not to hurt someone's feelings then it's not horribly bad. However, if you're doing it to get even or just to stir things up then that's going to create dreadful results in the end.
